The first law of thermal dynamics expresses the relationship between energy, heat and work. The internal energy of a system depends upon the heat absorbed or released by the system and the work done by or done to the system. Delta E=q+w For example, a ping pong player expends 35 kj/min during play.Which of the following represents Energy and which represents work? A. The paddle hits the ball B. muscle contraction C.

Metals are good thermal conductors — that is, when there is a temperature difference across their ends, they transfer energy very efficiently from the higher temperature end to the lower temperature end.  Based on this, would you expect a thermal conductor generally to have a low specific heat capacity (closer to sand) or a high specific heat capacity (closer to water)? A. Low specific heat capacity B. High specific heat capacity

150 grams of boiling water (temperature 100°C, heat capacity 4.2 J/gram/K) are poured into an aluminum pan whose mass is 970 grams and initial temperature 25°C (the heat capacity of aluminum is 0.9 J/gram/K). (a) After a short time, what is the temperature of the water? (b) What simplifying assumptions did you have to make? The thermal energy of the aluminum doesn't change. Energy transfer between the system (water plus pan) and the surroundings was negligible during this time. The...

Your car’s engine is a heat engine; it converts the thermal energy from burning fuel into energy to move your car and power its systems. On a cold winter day, you needn’t feel guilty about cranking up the heat in your car; running the heater doesn’t cost any additional energy beyond the small amount needed to run the fan. Explain why this is so.
