The volume and pressure of a gas are 4.30 m3 and 2.10 atm, respectively. (a) If this gas expands to two and one-half its initial volume while the pressure is constant, determine the work done on the gas. (b) On the other hand, if this gas is compressed to one-fourth its initial volume while the pressure is constant, determine the work done on the gas.
