Chapter 9 Section 2 Defining Heat and Energy • Heat is the energy transferred between objects because of a difference in their temperatures. • From a macroscopic viewpoint, energy transferred as heat tends to move from an object at higher temperature to an object at lower temperature. © Houghton Mifflin Harcourt Publishing Company

Chapter 9 Section 2 Defining Heat and Energy, continued • Just as other forms of energy have a symbol that identifies them (PE for potential energy, KE for kinetic energy, U for internal energy, W for work), heat is indicated by the symbol Q. • Because heat, like work, is energy in transit, all heat units can be converted to joules, the SI unit for energy. © Houghton Mifflin Harcourt Publishing Company
