Term
Thermal Expansion (Linear) 

Definition
Change in length = Linear expansivity of material X Original Length X Change in temperture 


Term
Thermal Expansion (Cubical) 

Definition
Change in Volume = Cubical expansivity X Original volume X Change in temperture 


Term

Definition
When a canister is heated then the molecules gain more energy meaning when they hit against the sides the energy increases 


Term
Specific Heat Capacity: The amount of heat required to raise the temperature of 1 kg mass by 1oC 

Definition
Specific heat capacity= Heat in (J)  mass X Change in temperture 


Term
Thermal Capacity: amount of heat require to raise the temperature of a substance of any mass by 1oC 

Definition
Energy Thermal Capacity =  change in tempertute
