Term
 Specific Latent Heat
Definition
 the amount of heat required to change the state of 1kg of a substance without changing its temperature
Term
 Specific Heat Capacity
Definition
 the measure of the heat energy required to increase the temperature of 1kg of a substance by 1 Celsius
Term
 Formula of Specific Heat Capacity
Definition
 C = E／m x change in temperature
Term
 Formula of Specific Latent Heat
Definition
 E = m x L
Term
 Effects on pressure of a gas when temperature changes
Definition
 an increase in temperature of a gas of fixed volume, the particles of a gas to gain kinetic energy, the pressure of a gas increases (more frequent collision)
Term
 Effects on pressure of a gas when volume is changed
Definition
 a decrease in volume of a gas of fixed temperasure, the particles of a gas, the pressure of a gas increases (more frequent collisions)
Term
 a formula of relationship between pressure and volume
Definition
 P1 x V1 = P2 x V2
Term
 Identify this statement is correct or incorrect.     In each change of state there is a transfer of thermal energy with a change in temperature.
Definition
