How much work is done when a tire's volume increases from 35.25 x 10–3 m3 to 39.47 x 10–3 m3 at a pressure of2.55 x 105 Pa? Is work done on or by the gas?

Heat is added to an open pan of water at 100.0oC vaporizing the water. The expanding steam that results does 43.0 kJ or work, and the internal energy of the system increases by 604 kJ. How much energy is transferred to the system as heat?

Helium in a top balloon does work on its surroundings as it expands with a constant pressure of 2.52 x 105 Pa. The balloon's initial volume is 1.1x 10–4 m3, and its final volume is 1.5x 10–3 m3. Determine the amount of work done in the balloon.

A system of gas in a piston releases 320 J of heat energy. There is 250 J of work done on the gas as it undergoes compression. If the initial internal energy of the gas is 631 J, what is the final internal energy of the gas?

In one cycle, an engine burning a mixture of air and methanol absorbs 525 J and expels 415 J. What is the engine's efficiency? How much net work is done?

A gas in enclosed in a cylinder fitted with a light piston at a pressure of 1.01 x 105 Pa. When 5.9 x 106 J of heat is added to the gas, the volume observed increased slowly from 12.0 m3 to 18.2 m3.

a. How much work is done by the gas?b. What is the change in internal energy of the gas?

A gas expands when 606 J of energy is added to it as heat. The expanding gas does 418 J of work on its surroundings. 

a. What is the change in internal energy of the gas?

b. If the work done by the gas were 1245 J, how would that effect the change in internal energy?

The energy provided each hour as heat to the turbine (power provider) in a nuclear power plant is 9.5 x 1012 J. If 6.5 x 1012 J of energy is exhausted each hour from the engine as heat what is the efficiency of the engine?

2800 J of heat is put into an engine but only 1250 J of work is produced.

a. How much energy is wasted in the form of heat in this engine? 

b. What is the efficiency of this engine?
