Guided Reading and Study Workbook (pages 131 - 134 & 135, 139 - 142) • Thermal energy flows from a higher to a lower temperature. • Energy will not spontaneously flow from a lower temperature to a higher temperature. • It is impossible to build a machine that does nothing but convert thermal energy into useful work.
 * 3.03 ** Investigate and analyze transfer of energy by heating:
 * Differentiate among conduction, convection, and radiation energy transfers.
 * Investigate the interaction between substances of different temperatures.
 * Explain why no machine can be 100% efficient.
 * Differentiate between heat and temperature.
