Thermal energy flows from...

• Objects at a higher temperature to objects at a lower temperature

• Objects at a lower temperature to objects at a higher temperature

The rate of thermal energy transfer is greater when...

• The difference in temperature between the objects is smaller

• The difference in temperature between the objects is greater

• Both objects are far apart

• One object is much bigger than the other

Thermal equilibrium between two objects occurs when...

• The heat of both objects is the same

• The temperature of both objects is the same
