Key terms
specific heat capacity
The energy needed to raise the temperature of one kilogram of a substance by one degree Celsius.
temperature change
In Temperature changes in a system and specific heat capacity, temperature change means in Temperature changes in a system and specific heat capacity, temperature change means the difference in temperature of a substance before and after energy transfer. Use this term when explaining calculate temperature change when energy change, mass and specific heat capacity are known in Internal energy and energy transfers. It is curriculum-specific for AQA GCSE Physics 8463 because it links the word to the approved objective rather than a vague everyday meaning.

specific heat capacity
The energy needed to raise the temperature of one kilogram of a substance by one degree Celsius.
thermal energy change
The amount of energy transferred to or from a system due to a temperature change.
specific heat capacity
The energy needed to raise the temperature of one kilogram of a substance by one degree Celsius.
thermal energy change
In Temperature changes in a system and specific heat capacity, thermal energy change means the amount of energy transferred due to a temperature change in a substance. Use this term when explaining required practical activity 1: determine the specific heat capacity of one or more materials in Internal energy and energy transfers.

insulation
Material used to reduce the rate of heat transfer, helping to maintain temperature during specific heat capacity experiments.
specific heat capacity
The energy needed to raise the temperature of one kilogram of a substance by one degree Celsius.
thermal energy change
The amount of energy transferred due to a change in temperature, calculated using mass, specific heat capacity, and temperature change.
specific heat capacity

It is curriculum-specific for AQA GCSE Physics 8463 because it links the word to the approved objective rather than a vague everyday meaning.
specific heat capacity
The energy needed to raise the temperature of one kilogram of a substance by one degree Celsius.
energy transfer
The process of energy moving from one system or object to another, often resulting in a change in temperature or state.
specific latent heat
The energy needed to change the state of one kilogram of a substance with no change in temperature.
energy transfer
The process of energy moving from one system or object to another, which can change the state or temperature of the substance.
specific latent heat of fusion
The energy required to change one kilogram of a substance from solid to liquid at its melting point without changing its temperature.
specific latent heat of vaporisation
The energy required to change one kilogram of a substance from liquid to gas at its boiling point without changing its temperature.
specific latent heat
The energy needed to change the state of one kilogram of a substance with no change in temperature.
energy for a change of state
The total energy transferred during a change of state, calculated as mass multiplied by specific latent heat.
specific latent heat
