If the substance is water, this is the kilocalorie (1000 calories). One calorie is the heat to raise one gram of water by 1 deg C. Other substances don't have the same specific heat capacity as water, so you have to correct for that, first find out the heat capacity (specific heat) for the substance you are dealing with.

Why does the amount of water affect time it takes to boil?
The basic formula which describes the energy required to raise the temperature of a substance is ΔE=mcΔθ. where: ΔE = Difference in energy m = mass of the substance c = specific heat capacity of the substance Δθ = change in thermodynamic temperature without any calculation, it is clear that if the change in temperature is the same (i.e. from room temperature to boiling point); and the specific heat capacity is the same; the more of the substance that is being boiled; the more energy is required. If the device which is boiling the substance is at a constant power, whether it be a burner or a kettle, the more energy required to boil the substance, the more time it will take to boil so long as the power is held constant.
Latent heat is the energy required for 1 kg of a substance to change?
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
Is temperature a form of energy?
Temperature is not a form of energy, but a measurement of energy (specifically, heat energy). You can't add temperature to a substance, because every substance already has a temperature, whether it be at -50o C or 900o C. However, you can add heat to change the temperature.
What does temperature have to do with energy?
no, temperature is one form of energy, heat.
What is the energy required to go from liquid to gas called?
The latent heat of vaporization
What is specific heat a measure of?
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
Is Temperature a measure of the amount of heat stored in a 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).»
What is a measurement of heat.?
A measure of the heat required to raise the temperature of a substance
How does temperature relate to amount of energy present in a substance?
Higher temperature means greater energy content compared to a lower temperature. The energy required to change the temperature is proportional to the mass of the system, the specific heat capacity, and the temperature change.
What is substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
What is the energy required to change a substance from a solid to a liquid WITHOUT changing it's temperature?
magic of coarse!
What is specific latent heat.?
It is the amount of energy required to change the state of 1kg of a substance with no change in temperature.
What is the measure of the kinetic energy of the particles of a substance?
Temperature is the measure of the average kinetic energy of the molecules in a substance.
Latent heat is the energy required for 1 kg of a substance to change?
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
Does temperature have a higher amount of thermal energy in a substance?
The higher of the temperature of a substance, the more thermal energy it has.

What does the latent heat of fusion represent?
The energy required to melt a substance. (Apex)
