Specific Heat Capacity

Definition



The energy required per unit mass of a substance to change its state without any change in temperature (Jkg-1)

Term

Definition


The process by which a liquid becomes a gas, at a temperature below its boiling point

Term

 

 

Define Internal Energy

Definition


The sum of the random distribution of the kinetic and potential energies of the atoms or molecules in a system

Term



Define Latent Heat of Fusion

Definition



The energy absorbed by a substance to change its state from solid to liquid without any change in temperature

Term

Definition



The energy absorbed by a substance to change its state from liquid to gas without any change in temperature

Term



Define Specific Latent Heat

Definition


The energy required per kilogram of the substance to change its state without any change in temperature (Jkg-1)

Term


Define Thermal Energy

Definition


Energy transferred from one object to another because of a temperature difference; another term for heat energy

Term



Define Thermal Equilibrium

Definition



A condition when two or more objects in contact have the same temperature so that there is no net flow of energy between them

Term



Define Thermodynamic Scale

Definition



A temperature scale where temperature is measured in kelvin (K)

Term

 

What does the Kinetic Model allow us to explain?

Definition


Allows us to explain behaviour and macroscopic properties in terms of the behaviour of molecules

Term

Definition




(See diagram in books)

Term

 

 

What is Brownian Motion?

Definition


Discovered by Robert Brown, this is a theory that supports the Kinetic Theory and can be observed using smoke particles under a microscope
