The amount of heat in a substance depends on many factors. What one must understand, however, is that Temperature differs from Heat in a Thermodynamic system by definition. Heat is the amount of energy transfer in a system. Basically, two substances always attempt to reach a temperature which is homogeneous throughout both substances at which it is considered to be at equilibrium. If the substance in question is not in an adiabatic environment (where there is no change in heat), then the substance is affected by the individual temperatures of every single other substance inside the environment. Picture a metal brick at a homogeneous temperature of 200 degrees Fahrenheit and a metal brick of the same type at a homogeneous temperature of 0 degrees Fahrenheit. Some factors to consider would be the air temperature which, initially, let's say was 70 degrees Fahrenheit. The 200 degree brick will attempt to approach equilibrium with the air around it. Typically this means that the air immediately next to the brick with heat up while the brick will cool down. The heated air will then heat up the air directly next to it, while the air directly next to the brick will cool down to attempt to match temperatures. This chain reaction continues until the heat is negligible. The same sort of thing occurs with the other brick in that the air next to brick 2 (the cooler brick) will try to reach equilibrium with the brick itself. This continues in the same pattern as with brick 1 (the hotter brick). This whole reaction has been described (badly, sorry) in a series of paused frames. This means that time is another factor as the system will, if given enough time, eventually reach equilibrium. After all this to consider, the factors which I have expressed seem to be Time, Temperature of other substances, Distance between the subject substance and the next substance (which can be seen to be expressed as density in a given volume of the environment), The ability for a substance to retain heat, along with some others which I have most likely forgotten. As a disclaimer, I am a 16 year old kid in 11th grade so I may be wrong about this. PLEASE make corrections to this if you see something that doesn't make sense.

What does heat content depend upon?
it depends on temperature.
What are 4 factors upon which a substances state depends?
It's Energy state (Temperature)Energy State of environment (Temperature)Mechanical pressure (compression, air pressure, etc.)properties of the substance (composition, heat coefficient, melting point, etc.)
How does cooling affect the volume of the substance?
No. Actually evaporation is the vaporisation from the surface of liquid, so its not matters that how much volume is the water of, because the rate of evaporation is depends upon the area of surface.
Separation of substance based upon particle size?
It's called sifting.
Name the four factors upon which a substance's state depends?
State of matter can depend on several things. These things include temperature, particle arrangement, motion of particles, and pressure.
Why specific heat capacity increase with temperature?
Specific heat capacity is by definition a per-unit-mass property. Therefore it does not depend on the mass of the substance.
What Amount of energy needed to raise 1 kg of a substance 1 Celsius?
Specific heat (Cp)= the amount of heat needed to raise 1 g of a substance 1 degree C. CP of Sc= 0.568 J/g oC
What is thermal conductivity dependent on?
Thermal conductivity depends upon the nature/identity of the substance and upon temperature. In some cases, such as wood, it depends upon the conduction heat transfer direction with respect to the material structure.
The absorption of heat by any substances is dependent upon?
its specific heat capacity
Is there a DSMIV code for substance abuse?
There are a plethora of DSMIV substance abuse codes. It all depends upon the diagnosis. They are specific to the substance being abused, there is also one for polysubstance abuse when one substance does not qualify. Then there is also abuse versus dependence. So again, it all depends.
Why the specific heat capacity of a substance depends upon phase?
The capacity for an object to be heated and retain heat is determined by its phase because of the way the different phases of matter move. The more freely the molecules are able to move around (like in a gas), the more likely the excited (or warmed up) molecules will leave the group, causing the heat to dispress more quickly.
What determines refractive index?
It depends upon the material of the substance
Why may the temperature of a substance change when energy is added?
Thermal energy of a substance is determined by the movement of the molecules and the potential energy of the arrangement of molecules. Heat transfer will stop when thermal equilibrium is reached. It depends upon the substance how long that takes.
What does heat content depend upon?
it depends on temperature.
How are specific heat of water and ice the same?
That is how specific heat is defined. When you measure something you have to measure it relative to some point of reference. In specific heat it was agreed upon that water was to be the standard and its specific heat would be one. Therefore everything else is measured relative to water.
How many pounds are equal to 10 pints?
That depends upon what substance makes up the 10 pints. Mass (pounds) and volume (pints) are related by density (pound per pint) which depends upon the substance (and pressure/temperature).
What is Heat transfer process that depends upon the movement of air?
convection
