Heat CANNOT be transferred through a LIQUID by which of the following?

radiation\n\nbecause the above answer is correct...radiation is through AIR, not liquid\n\nconduction:  cold water cools you down, right?  conversely you heat the water\n\nconvection:  is specifically transfer of heat THRU LIQUID...so that works\n\ncondensation:  directly related to water vapor which is liquid, again

Water evaporates at 100 degrees, celsius, so the liquid water you touched wouldn't be any hotter than that. The metal, on the other hand, does not. So it would be as hot as the object which is heating it.

False\n\nWhen steam is cooled to water, both can be 100 degrees C, but steam must give off energy to become a liquid.  The opposite is easier to understand.  When you are boiling water, the steam that escapes will be 100 degrees C, but will have much more energy than the 100 degree water.\n\nIn both of these cases, the energy put into or taken out of the water is used to change its phase, without changing its temperature.

Are you asking about thermal conductivity or specific heat?\nAnd why are you not doing the research you should be doing:\nhttp://www.engineeringtoolbox.com/specific-heat-metals-d_152.html\nhttp://www.engineeringtoolbox.com/thermal-conductivity-metals-d_858.html

Conduction- the transfer of heat to a particle of matter without the movement of matter itself.\n\nConvection- the transfer of heat to a particle of matter with the help of movement of the matter.\n\nRadiation- the transfer of energy through electromagnetic waves.

Water always evaporates no matter what is its temperature. Evaporation is NOT related to heat. Even at 1C it can evaporate. Water boils at 100C but evaporation occurs at every temperature.

That question cannot be answered with the limited amount of information provided.  However,  if you consider the speed of the particles...then heat is the answer.  Considering anything else requires more information.

fluids - convection is due to the movement of molecules

You must approach this question with an understanding of energy conservation. Change in Energy = mass*heat capacity*change in temperature, where heat capacity = 1.00 for pure water. By evaluating your conditions with the above definition of thermal energy, it will show that you must supply 2 calories of heat to the system.\n\nIf you were to add another substance to the original system. You would once again approach the problem using energy conservation. The energy of a hot liquid (mass1*heat capacity*change in temperature) + the energy of a cold liquid (mass2*heat capacity*change in temperature) = mass(1+2)*heat capacity*change in temperature.\n\n-Christopher

conduction in solids, convection of fluids (liquids or gases), and radiation through anything that will allow radiation to pass.

All 3 are different modes of transferring heat\n\nConduction: This is generally seen in metals, because they have free ions. When a metal is heated, the free ions which are in the lower orbit get excited. These ions move to the higher orbit and in turn excite the ions in the adjoining molecule. In this way heat is transferred. This is not seen in non-metals because they don't have free ions.\n\nConvection: Seen in water, air and other liquids and gases. Convection takes place due to imbalance in temperature in different parts of the liquid (or gases). Due to heat being applied, the hot liquid (or air) goes upwards and the cooler liquid (or air) goes downwards, thus creating a cyclic current. As this liquid gets heated further, it moves upwards again and the now cooler liquid goes downwards.\n\nRadiation: It is the only form of transfer of heat that DOES NOT necessarily require a medium to transfer heat. Radiation takes place in the form of electromagnetic waves. Radiation can even transmit through vacuum, unlike Conduction and Convection which require a material medium. Eg. Radiation of heat by the Sun to Earth.

this re minds me of a kind of heat called latent heat.this is the heat a subtance requires to change it state without changing it temperature,so water changes from liquid to steam at the same temperatutre if it assumes it latent heat of vapourization.thus water could be liquid at 100*c and also steam at the same temperature.

Your answer depends on the nature of your problem, so you'll want to give more info if you want a complete answer.  The specific heat capacity you use depends on which substance is being heated up or cooled off.  The mass will be the mass of the substance that is being heated up or cooled off.\n\nOne exception that frequently occurs is when you are dissolving a substance in water.  Most problems will assume that the solution has the density and specific heat capacity of pure water.  So in other words, if you dissolve 3 grams of ammonium chloride in 100 mL of water and watch the temperature go down, most instructors would want you to use a mass of 100 grams (instead of 103) and the specific heat capacity of water 1.00 cal/g C or 4.184 J/g C if you're working in joules.\n\nHope this helps...this is the best I can do without more info about the problem.

Well, I can give you three nonflammable liquids that are mutually immiscible...\n\nwater\ncarbon tetrachloride\nmercury\n\nMost things that are immiscible with water tend to be nonhalogenated solvents and therefore flammable.

Quantity of heat (Q), measurement = joule (J)\nSpecific heat capacity in liquid, measurement = c/(kJ kg^-1)

If you are dealing with a reaction involving ammonium carbonate in solution, and are then measuring the temperature rise, you need the heat capacity of water, not ammonium carbonate!\n\nPlease post the whole problem if that is not enough to get you started.

The answer should be A.\n\nAverage kinetic energy of a substance is related to the speed of the particles moving in it and the temperature of the substance.\n\nAs the particles in the a substance moves faster, the average kinetic energy of the substance increases.  So does the temperature.\n\nWhen a substance changes phase, the temperature will remain constant.  This means that the average kinetic energy is also constant during this process.  Hence, B is wrong.\n\nWhen thermal energy is being transferred out of the substance, one could understand it as taking out some particles out of the substance.  So what is changed here?  I would think that the total kinetic energy is being changed, since some particles have been taken away.  But the taking away of the particles would not affect the speed of the remaining particles.  The AVERAGE kinetic energy should remain unchanged.  Hence, C is also wrong.
