Question

An ideal gas in a balloon is kept in thermal equilibrium with its constant-temperature surroundings. How much work is done if the pressure is slowly reduced and the balloon expands to 5.0 times its original size? The balloon initially has a pressure of 815.0 Pa and has a volume of 0.70 m3.        -8.0 J
       -920 J
       -1,000 J
       -2,900 J An ideal gas in a balloon is kept in thermal equilibrium with its constant-temperature surroundings.
