The frictionless moving piston of a horizontal cylinder seals off 1.0 kmol of a monatomic gas at 0⁰ C. The gas is heated to 143⁰ C. The gas is heated to 143⁰ C. The piston moves against the constant external pressure of 1.0 bar, so that the gas volume increases. What is the volume of the gas after heating in cubic meters?
