Physics · Thermodynamics
A reversible adiabatic path, on a P-V diagram, for an ideal gas passes through state A where P = 1 MPa and V = 0.0025 m 3 . Given that the ratio of specific heats for the gas is 1.4, the slope of the path at A is:
- 14 × 10 5 kPa/m 3
- 2-4 × 10 5 kPa/m 3
- 3-5.6 × 10 5 kPa/m 3✓
- 45.6 × 10 5 kPa/m 3
Correct answer
-5.6 × 10 5 kPa/m 3
