← A flat plate of area 0.1 m² is pulled at a steady 0.5 m/s over a layer of oil 1 mm thick, which lies on a fixed flat surface. The coefficient of viscosity of the oil is 0.2 Pa s. The force needed to keep the plate moving isAn ideal monatomic gas goes from state A (2 × 10⁻³ m³, 3 × 10⁵ Pa) to state B (5 × 10⁻³ m³, 1 × 10⁵ Pa) along the straight line shown in the pressure-volume diagram. The work done by the gas, and the heat it absorbs, are →
