specific heat capacity and specific latent heat

• give factors affecting temperature change of system

  mass, type of and energy input of heated substance
• describe specific heat capacity

  amount of energy required to raise temperature of 1 kg of substance by 1 degree
• describe latent heat

  energy required for substance to change state
• describe change of state of substance

  energy supplied affects internal energy with constant temperature due to energy used to break / form bonds
• describe specific latent heat

  amount of energy required to change state of one kg of substance with no change in temperature
• describe specific latent heat of fusion

  energy required to change state of one kg from solid to liquid with no change of temperature
• describe specific latent heat of vaporisation

  energy required to change state of one kg of substance from liquid to vapour with no change of temperature
