Specific heat capacity 
The amount of heat energy required to raise the temperature of a substance by one degree Celsius
Calculating specific heat capacity
1. Mass of substance
2. Change in temperature
3. Heat absorbed
Heat energy 
The energy transferred due to a temperature difference
Calculating heat energy 
1. Mass of substance
2. Change in temperature
3. Specific heat capacity
Specific heat of copper
The amount of heat energy required to raise the temperature of 1 gram of copper by 1 degree Celsius
Calculating change in temperature
1. Heat transferred
2. Mass of substance
3. Specific heat capacity
Calculating heat to change ice to water to steam
1. Heat to raise ice to 0°C
2. Heat to melt ice
3. Heat to raise water to 37°C
Molar heat of vaporization 
The amount of energy required to convert one mole of a liquid to a gas at its boiling point
Specific heat of liquid water
The amount of heat energy required to raise the temperature of 1 gram of liquid water by 1 degree Celsius
Specific heat of water vapor
The amount of heat energy required to raise the temperature of 1 gram of water vapor by 1 degree Celsius
Solid phase 
The state of matter with a definite shape and volume
Liquid phase 
The state of matter with a definite volume but no definite shape
Gas phase 
The state of matter with no definite shape or volume
Triple point 
The temperature and pressure at which the solid, liquid, and gas phases of a substance coexist in equilibrium
Melting point 
The temperature at which a solid transitions to a liquid at a given pressure
Boiling point 
The temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid, and bubbles of vapor form inside the liquid
Critical temperature 
The temperature above which a gas cannot be liquefied, no matter how much pressure is applied
Sublimation 
The direct transition of a substance from the solid phase to the gas phase, without passing through the liquid phase
