week 18 vocabulary

represent the average Kinetic Energy of the particles that make up an object

• temperature

• specific heat capacity

• volume

• phase change

has neither a definite volume nor a definite shape.

• Gas

• Liquid

• Solid

the amount of space an object takes up

• Volume

• Temperature

• Phase Change

increase in a material’s volume when the temperature is increased

• thermal expansion

• thermal contraction

decrease in a material’s volume when the temperature is decreased

• thermal expansion

• thermal contraction

has a definite shape and volume

• Solid

• Liquid

• Gas

amount of thermal energy it takes to increase the temperature of 1 kg of material by 1°C

• Phase Change

• Specific Heat Capacity

• Temperature

has a definite volume but takes the shape of its container.

• Solid

• Liquid

• Gas

a change from one state (solid or liquid or gas) to another without a change in chemical composition.

• phase change

• solid

• liquid

• gas

When a solid is heated, the particles are given more energy and start to vibrate faster. the solid melts into liquid.

• Melting

• Freezing

• Evaporation

• Condensation
