A cylinder with volume V0 has enclosed air in it. Air temperature is T and pressure is p0. The air is compressed to 1/6 of original volume while keeping constant temperature. After that, we quickly open and close the cylinder which causes air expansion to double of its original volume. There will be no exchange of warmth between the air and its surroundings. a) determine the temperature after expansion ? b) size of work the gas did when compressed?  c) size of work the gas did when expanded? d) determine final work made by the gas during the whole event?
