They point toward positive charge B. They start on positive charge and end from negative charge C. They start on negative charge and end from positive charge

Explanation / Answer

7. The correct answer is Option C. If the heat of the body is equal to that of its surroundings, it will gain heat equal to its surroundings. (The question appears faulty)

8. The correct answer is Option C. If the temperature of the two objects is lower than that of the environment, their final temperatures will be smaller. (Some information seems to be missing from the question)

9. The correct answer is Option B. Heating an object cannot decrease the temperature.

10. The correct answer is Option A. The sun heats the earth through conduction.
