371530 Air in a cylinder is suddenly compressed by a piston, which is then maintained at the same position. With the passage of time

1 The pressure increases
2 The pressure decreases
3 The pressure may increase or decrease depending upon the nature of the gas
4 The pressure remains the same
PHXI12:THERMODYNAMICS

371531 One mole of an ideal monoatomic gas is heated at a constant pressure of one atmosphere from \(0^\circ C\) to \(100^\circ C\). Then the change in the internal energy is

1 \(20.80\,joules\)
2 \(12.48 \times {10^2}\,joules\)
3 \(8.32 \times {10^2}\,joules\)
4 \(6.56{\rm{ }}\,joules\)
PHXI12:THERMODYNAMICS

371532 A frictionless piston-cylinder based enclosure contains some amount of gas at a pressure of \(400\,k\,Pa\). Then heat is transferred to the gas at constant pressure in a quasi-static process. The piston moves up slowly through a height of \(10\,cm\). If the piston has a cross-section area of \(0.3\;{m^2}\), the work done by the gas in this process is

1 \(12\;kJ\)
2 \(6\;kJ\)
3 \(24\;kJ\)
4 \(7.5\;kJ\)
PHXI12:THERMODYNAMICS

371533 A diatomic gas is heated at constant pressure. What fraction of the heat energy is used to increase the internal energy?

1 \(3 / 7\)
2 \(3 / 5\)
3 \(5 / 9\)
4 \(5 / 7\)
