2C: how heat affects the temperature

boil

to convert a substance from liquid to gas at its boiling point

condense

to convert a substance from gas to liquid

evaporate

to convert from liquid to gas only at the liquid’s surface due to high-energy particles in the liquid escaping

freeze

to convert a substance from liquid to a solid at its freezing point

latent heat

the heat absorbed or released to change the state of a substance

melt

to convert a substance from solid to liquid

specific heat capacity

the heat per unit of mass needed to increase the temperature of a substance by one kelvin (or degree Celsius)

latent heat of fusion

the heat per unit of mass required to convert a given substance from a solid into a liquid

latent heat of vaporisation

the heat per unit of mass required to convert a given substance from a liquid into a gas

state change

the process of changing between different states of matter

specific heat capacity

Q= mcΔT; Q= heat transferred, m= mass, c= specific heat capacity, ΔT, Tf-Ti= change in temperature

latent heat

Q=mL; Q= heat transferred, m= mass, L= latent heat
