what is latent heat ?
406343
it's heat absorbed or radiated during a change of a phase at constant temperature/pressure.

Perhaps the asker does mean phase. (The distinction is: "Phases are sometimes called states of matter, but this term can lead to confusion with thermodynamic states. For example, two gases maintained at different pressures are in different thermodynamic states, but the same "state of matter". -wiki)\nWhen a substance changes from the solid to the liquid phase, the separation between the particles (atoms or molecules) increases. It takes energy to make this increase because of interatomic/intermolecular attraction. The energy is supplied as heat removed from the environment. This heat is called the latent heat of fusion.\nThe same argument applies to a phase change from liquid to gas. Particles are still more separated in a gas. The heat required to accomplish this is called the latent heat of vaporization. See the ref. for a more complete explanation.

The cold is less heat\n& since the heat is energy so cold is also an Energy

what's the heat source?

A reaction which gives out heat is known as 'exothermic'.\n\nhttp://en.wikipedia.org/wiki/Exothermic\nhttp://en.wikipedia.org/wiki/Exothermic_reaction\n\nA reaction which seems to absorb heat is known as 'Endothermic'\n\nhttp://en.wikipedia.org/wiki/Endothermic\nhttp://en.wikipedia.org/wiki/Endothermic_reaction

Thermal energy is energy associated with temperature.  This corresponds to a measurement of how much the particles in a material 'wiggle'.  The more the wiggle the higher their temperature.  This wiggling causes the emmision of EM waves or light according to a blackbody curve.  Higher temps, with more wiggling, will emit more total energy and more photons at shorter wavelengths.  The hotter the object, the more infrared radiation it emits, however it will also emit more of every other wavelength too.  The peak wavelength shifts to shorter wavelengths ( higher energies) at higher temperatures.

According to http://en.wikipedia.org/wiki/Latent_heat  the Heat of Vaporization for Ammonia is 1369 Joules/gram  So the answer is 55.6 * 1369 joules.

generally speaking it goes from greatest conductivity = lowest temprature to least conductivity = highest temp.  Heat increases the randomness and thereby slows conductivity.

Heat is the measure of internal energy that an object has.  Heat flows from a hotter object to a colder object only.  The internal energy flows from the higher level to the lower level.  This is similar to flowing water.  The water in a lake at the top of the hill has more potential energy than the water in the lake at the bottom of the hill.  The water will flow downhill only.  The water flows from the location where it has a higher energy level to the location where it can have a lower energy level.

false - temperature is a measure of heat

Since there is no temperature change in the substance, only a phase change (solid --> liquid), all you need to use is,\nQ = Lm\nwhere Q is the heat energy, L is the latent heat of fusion, and m is the mass of the substance.\nI dont happen to know the latent heat of fusion for water (I think it is like 2260 J/g, maybe), but I am sure it is in your book somewhere.\nJust plug the values into the formula and you are set.\n\nEDIT:\nThe Latent heat of fusion of water is 333 J/g.\nThe latent heat of vaporization is 2260 J/g.

The one that heats up faster AND to higher temperatures is soil.\n\nWater can not gain or lose heat as quickly as soil due to latent heat. Water absorbs heat until it reaches the next phase change (vaporization) in which the water changes state.
