What is thermal equilibrium?

• When two objects reach the same temperature and no heat flows between them

• When an object reaches its highest possible temperature

• When heat flows from a cooler object to a warmer one until they are the same temperature

• When an object's temperature decreases until it matches the temperature of its surroundings

Which method of heat transfer does not require matter?

• Conduction

• Convection

• Radiation

• Insulation
