The video tutorial explores the concept of heat as the transfer of thermal energy between objects. It demonstrates this through an experiment with a paper cup and water, showing how water prevents the cup from burning. The tutorial explains thermal energy as the motion energy of molecules and describes the three methods of heat transfer: conduction, convection, and radiation.

What is heat primarily described as in the video?

• The energy stored in an object

• The transfer of thermal energy between objects

• The temperature of an object

• The light emitted by an object
