Unformatted text preview: 4. The principle o± conservation o± energy is that energy is never: a) adequately defned. b) destroyed, but can be created. c) created or destroyed. d) created, but can be destroyed. e) destroyed. 007 qmult 00132 1 1 4 easy memory: conservation o± energy 2 Extra keywords: physci 5. In the physics, the conservation o± energy means energy: a) shouldn’t be wasted on cars. b) is never destroyed. c) is never created. d) is never created or destroyed. e) is perpetually created. 007 qmult 00134 1 1 1 easy memory: energy conservation implication Extra keywords: physci KB-72 6. The total energy o± a closed system (i.e., a system which nothing enters or leaves) is: a) conserved. b) annihilated. c) created. d) combusted. e) eviscerated. 007 qmult 00136 1 1 2 easy memory: universe and conservation o± energy Extra keywords: physci KB-92-5 7. I± the universe as a whole is a closed system, then current physical law tells us that its total energy is:...
