There are two ways to keep something cold.\n\n1.  Insulate the container to keep the heat outside.  Standard household insulation, that can be found at Home Depot, will work for this.  With the reflective coating on the outside it will help to reflect any heat away from the container.  The building industry measures the value of this resistance in R factors.  Another good way to do it is to get a normal Styrofoam cooler and improve it by wrapping it in aluminum foil.\n\nAndrew has a good idea of using a thermos.  A thermos is a metal container with another container that can fit inside.  There needs to be an air gap.  When you seal the two containers together then the thermos will work.  One of the best insulators is a gap of air, or better yet a vacuum.  Insulated Windows use the same principle.  With a sealed air gap of 1/4” between two panes of glass the insulation is much better than if the two panes of glass were placed next to each other.\n\nOne way that insulation works well is to trap or allow air gaps inside the material.  Spray on insulation is a binary chemical that forms a very light Styrofoam like material.  The advantage of this is that it can be directly sprayed in the area to be insulated, and the excess can be cut off.  Since it is a fast drying gluey substance it dries as soon as it makes contact with the air.  In this way the material will stick to a wall.  As the material is exposed to the air then it foams up filling the cavity, and trapping air bubbles inside the material.  The expanding foam is not that powerful so if you use it in a pocket like between the inside drywall and the outside of a wall then it won’t push the drywall away from the studs to which it is nailed.  Styrofoam is so light because of all the air trapped inside.  You can illustrate this with a can full of marbles.  The marbles are the plastic molecules, and the gap between them is the air gap.  Pour water into the can until it is full.  Then drain the can and measure the amount of water.  This shows how much air can be trapped inside the Styrofoam.\n\nThe insulation you buy from Home Depot has air gaps between the fiberglass layers and inside those layers.  The outer coating has a watertight seal with a reflective membrane to keep the water out and reflect the heat away.  If the insulation gets wet then the air gaps inside of it can disappear and the layers can be compressed.\n\n2.  Remove the heat from the object.  The old way was to put ice on it or inside a container.  The newer method is to physically remove the heat and send it outside.  In the old series the Honeymooners, with Jackie Gleason, their icebox had a larger chamber for ice, with a pan to drain it in.  The refrigerator was below the ice chamber and the entire box was insulated.  As the ice absorbed the heat it melted sending the warmer water out and into the drain pan.\n\nA refrigerator uses Boyle's Law on gases and the second law of thermodynamics to absorb the heat from the container and to send it outside where it is radiated away.  A gas like Freon is used because it has a melting point and a boiling point that are easily reached; of course with the CFC (Chlorofluorocarbons) problems Freon has been replaced by other gases.  The Freon, as a liquid, is circulated through a pipe into a chamber inside the container to be cooled.  Then the chamber is closed and a diaphram is moved increasing the volume of the container.  When this happens then the chamber and the material inside absorb heat.  The pressure change transferes the heat from the container into the chamber.  The chamber is then opened and the gas is forced out into the radiator by the pump.  As the gas is circulated through the radiator it loses its heat to the environment and can then be returned to the chamber.\n\nTo duplicate this for a science class the following materails are needed:  a bicycle pump, a therometer, air tight tube (like that used in aquiram pumps), a metal can (a soup can will work)

sun bathing is radiation. sun radiation travel through space(no air in space so it is pure radiation energy transfer), travel through air (in there also radiation is dominant ) then get in to your skin\n\nstroform is a good insulater. it has hollo set of chambers. in chambers covection can be done but cells prevent transfer of air further and convection is stoped. in the other hand conduction is prevented due to poor conductivity of material. radiation is not a problem when heat difference is not too much high and because radiation generated from a object is is propotional to absolute heat  of the object. in case of very high temperature allumenium foil is used to limit radiation.

warm  and i'm a guy.  \n\n\n(i do have to say this is a good question,  very interesting.)

not neccessarily, it really depends if your wearing shoes or not. of course your asking, how do i verify this?\n\nwell their is this thing called conductors and instulators. conductors means current can go through and insulators means it can't. the reason why humans get charged up because their friction causes electrons to build up in their body.\n\nso basically, touch someone else for fun and you might verify that shock.

Depends on what you mean by types.\n\nDo you mean the type of material used in constuction or the type of activity the building is intended for.\n\nMost large building use a chilled water system where they use chillers to cool water down to about 42 deg F then pump the water throught the building to air handler units which blow air across the coils filled with the water.  This heats the water, but cools the air.  As the air is circulated throughout the area the water is returned to the chiller to be recooled and the process starts all over again.\n\nHowever, an important point is capacity.  That will be determined by both what the intended use of the building is and what sort of material is used.

This ain't my forte, but here goes.\n\nAdiabatic expansion is like what my freezer and air conditioner use to cool things off.  They take a pressurized gas and let it expand, which drops its temperature.  Then they let this low-temperature stuff suck up the heat in my Ben & Jerry's or in my house.  If you've ever discharged a CO2 fire extinguisher or used a can of compressed air to clean your computer, the CO2 is so cold it condenses the water in the atmosphere or the air on your computer is very cold.\n\nIsothermal means the temperature stays the same.  So if your gas expanded and it didn't get colder, something else went on to provide the heat to keep the temperature the same.  \n\nMaking heat is work, in physics terminology, so the isothermal expansion required more work than the adiabatic expansion.

Different materials conduct heat at different rates.\n\nMetal, for example, is generally an excellent conductor of heat, meaning that when you place your hand on a metal doorknob, the metal conducts heat away from your hand at a much higher rate than of you were to grab an object made of less conductive material, such as wood.  The sensation you're calling "cool" or "cold" is simply heat being conducted away from your skin.  \n\nRemember, just as darkness is nothing more than the absence of light, cold is nothing more than the absence of heat.  So when you're touching a cold object, nothing is being imparted to your skin; all you're feeling is the heating leaving.\n\nRegards,\n\nKevinb671, Ph.D.\nSertufied Science Person

Well, gypsum is a good insulator.  Its resistance would depend on what impurities (such as moisture) were present in it.  \n\nIf you are planning on using this with high voltage,  you should be more concerned with the dielectric breakdown voltage than the resistance.  This is the voltage at which a material that is normally an insulator will begin to permit electricity to arc through it.  Check the link below for more information.

It meant the same thing as grounding yourself.  Your body is like a live battery and it can store charges (like a capacitor).  This charge caused static when you are in contact with espcially electronic devices like motherboard. The static discharging can reach a few thousand volts and could well destroy or burn small chipsets inside a motherboard, and rendered it useless.  \n\nYou should wear an antistatic wrist strap while handing PC boards.  This wrist strap will 'eat' the static charge in your body and discharge any static on the PC board.  It sells for about $2 at fry's electronic.\n\ngood luck

Wire gauge is selected based on current capacity and voltage drop. Insulation type is based on voltage, environment, and type of service. \n\nThere are published standards for many different applications. Safety factors are figured into the requirements.

It classic bavarian, a german dialect. It means "well it is nice today, for the sauna it think ist is too nice weather and too warm"\nNormally the dialect is not written(as far as I'm aware), but it is fun if you do as ther is no strict spelling
