What is the diffrence between temperature and heat?

Heat is a form of energy. \nTemperature is a measurement of the state of heat-energy in a certain body.

The temp. between hot water and steam is a big difference. Say that steam is at 400 degrees F and hot water is 180 degrees F, steam will boil your hand faster then hot water.

Do you know what "specific heat" means? It is the amount of heat required to raise the temperature of a certain amount of substance by 1 degree Celsius.\n\nWater has a very high specific heat compared to most other substances. That means it takes of lot of heat to change the temperature of water. If you ever tried to boil a big pot full of water, you know what I mean.

its the other way round. a thing is hot if its molecules are moving with a higher thermal velocity (prop to T^1/2). if you heat something its molecular vibrations go up in turn increasing its temperature.

A CPU, normally works between 100F & 140F. and your CPU temprature is OK. Older CPUs work near 100 and Faster CPUs work near 140. so don't worry about it.

thermodynamics?  heat transfer?  physics?

Specific heat varies with changes of composition and temperature. The specific heat of a material can be calculated by hand or by using a process simulator.\n\nThe attached link can be used to obtain specific heat (and other properties) for a handful of pure components.\n\nBest wishes !

There are temperature changes is most reactions becuase there is heat generated, known as the heat of reaction.

Heat is the kinetic energy of molecular motion. The molecules of a hot object are in rapid motion; the hotter, the higher the average speed and the greater the thermal energy. If the object is gaseous the motion consists of free-path travel and collisions with other molecules. If it is liquid the paths between collisions are shorter, and if solid the motion is vibrational with no secular movement.

Of course taking the temperature of anything will alter the temperature that you're taking. The question is how much. For most cases, the change is negligible, so we can take the measurement as the temperature of the object (here the object can be water).\n\nThe reason that there is a change to the temperature is because when you add your measuring device (here it would be a thermometer) to the water, the thermometer will either absorb or release some amount of heat, depending on its relative temperature to the water. The laws of thermodynamics states that a system will always seek to reach a state of thermal equilibrium (meaning that hot things will release heat to cool off, and cold things will absorb heat to warm up).

The answer goes back to what temperature measures.  Heat is actually the motion (really kinetic energy) of atoms (since we're talking about an element).  Lower heat (and lower temperature) mean less motion.\n\n-273 C (or 0 degrees Kelvin) is known as "absolute zero".  It is the temperature at which that heat motion stops and kinetic energy goes to zero.  Since an atom cannot have negative motion or negative mass, its kinetic also cannot be zero and therefor its temperature cannot be less than absolute zero.

Hi Kitty,\nHere is what, I think, you need.\n\nExothermic, dH < 0, Entropy increases (dS > 0), Reaction is spontaneous and dG < 0\n\nExothermic, dH < 0, Entropy decreases (dS < 0), Reaction is spontaneous only at low temps, if |T dS| < |dH|\n\nEndothermic, dH > 0, Entropy increases (dS > 0), Reaction is spontaneous only  at high temps, if T dS > dH\n\nEndothermic, dH > 0, Entropy decreases (dS < 0), Reaction is not spontaneous, dG > 0

false - temperature is a measure of heat

The temperature of any material is a measure of the average kinetic energy of all the atoms in the material. As you increase this kinetic energy (temperature) then the atoms are more energetic the atoms vibrate with more energy this means each atom takes up more space and so the total volume of the material increases aswell

To keep it simple, temperature doesn't travel only heat travels. It does so by conduction, convection or radiation.

exothermic means energy is given off, so it wud have a - sign\n\nendothermic means energy is absorbed and wud hav a + sign\n\nhope this helps!!

Neither. Let's have a given that 1 fridge is empty and at 40 degrees inside. The other fridge is full and at 40 degrees. The room that these 2 fridges are in is at 70 degrees. The difference in temperature is the cause for heat to flow from hot to cold. The fridges have insulation that has a certain resistance to heat flow. The heat will flow through the walls of the fridges the same, so then Q(heat flow)=A(area)x(T1(70 degrees)-T2(40 degrees))/R(resistance). The area of heat loss for both fridges are equal,the resistance of both fridges are equal, the temperature differential for both is equal,  so the amount of electricity needed to keep the fridges at 40 degrees is equal.
