Created by StemPy LabAn ideal monatomic gas expands slowly along a path on which stays constant. Which statement is correct for this expansion?
← All Quizzes
← A gas is taken round a cycle of three steps. From A to B its internal energy increases by 1500 J while it does 600 J of work. From B to C its volume stays constant and it gives out 2000 J of heat. From C back to A it is thermally insulated, so no heat flows. Which statement about the step from C to A is correct?One mole of an ideal monatomic gas is at 300 K and 1.0 × 10⁵ Pa in a thermally insulated cylinder. The pressure outside the piston is suddenly raised to 2.0 × 10⁵ Pa and then kept steady, so the gas is squeezed quickly until it is again at rest, at 2.0 × 10⁵ Pa. Ignore friction and the mass of the piston, and take R = 8.314 J/(mol K). Which of the following statements are correct? →
