Energy is transferred in solids by conduction, which means that

• heat travels in both directions.

• heat travels from the cooler object to the hotter object.

• heat travels from the hotter object to the cooler object.

• heat does not travel between objects of different temperatures.

The Law of Conservation of Energy states:

• Energy can created or destroyed but not transformed 
• Energy cannot be created or destroyed, it can only transformed
• Energy can't be created, destroyed or transformed
