  • The correct answer, therefore, is (D). 14. The amount of heat needed to raise the temperature of a substance over a specific temperature range is determined by multiplying the specific heat X the mass X the change in temperature. Q C X m X ~t, Q = 4.19 J/g.oC X 10.0 g X (50.0°C 30°C) = 838 joules The correct answer, therefore, is (C). 15.
  • 12. Within the photosystems, the critical conversion of solar energy to chemical energy occurs. This process is the essence of being a producer! Using Figure 10.13 as a guide, label the diagram and then explain the role of the components of the photosystem listed below. See page 193 in your text for the labeled figure. a.
  • Thermodynamics is the study of thermal, electrical, chemical, and mechani‑ cal forms of energy. The study of thermodynamics crosses many disciplines, including physics, engineering, and chemistry. Of the various branches of thermodynamics, the most important to chemistry is the study of the change in energy during a chemical reaction.
