Thermal Energy Transfer Quiz

This document contains a 9 question assessment about thermal energy transfer. It tests understanding of key concepts like: 1) Heat is the transfer of energy between objects at different temperatures when they are in physical contact. 2) For heat transfer to occur, the two bodies must be at different temperatures. 3) When energy is transferred to a substance as heat, the average kinetic energy of its particles increases. 4) Heat will spontaneously transfer from a higher temperature object to a lower temperature object. The assessment examines these concepts through multiple choice and short answer questions.
