Hot!
Heat energy is found everywhere, including the Sun?s rays and the Earth?s heat under the ground. This volume defines heat and thermal energy, explains the states of matter, explores measuring heat, and outlines other basic concepts of heat energy. Sidebars profile ways that heat is measured and explain concepts of thermal energy. Photographs illustrate common sources of heat energy that can be identified in everyday life.
