Heat is a measure of the molecular and atomic excitation of the substance, i.e. the degree of vibration that it has available to impart to other substances that it comes into contact with.
Temperature is not a measure of the amount of heat stored in a substance. It is the measure of the kinetic energy of the molecules of a substance.
A measure of the heat required to raise the temperature of a substance
The amount of energy it takes to change the temperature of a substance by a certain amount. How much energy it takes to heat a substance ~APEX
The ability of a substance to hold heat.
The energy required to boil a substance
The specific heat of the substance.
No. As Temperature isn't by any way a measure of how much energy is ''stored'' in a substance, it vary with the heat capacity of the said substance...«Heat capacity (usually denoted by a capital C, often with subscripts), or thermal capacity, is the measurable physical quantity that characterizes the amount of heat required to change a substance's temperature by a given amount. In the International System of Units (SI), heat capacity is expressed in units of joule(s) (J) per kelvin (K).»
heat
No.
That really depends on what you are trying to heat and how you are heating it.
Heat capacity depends on the substance's mass, the substance's specific heat capacity, and the temperature at which the substance is being heated. It is a measure of how much energy is required to raise the temperature of a substance by one degree Celsius.
