A gas goes from state 1 (20 $c m^{3}$ , 20 kPa) to state 2 (50 $c m^{3}$ , 60 kPa) by three paths: I a straight line; II first up at 20 $c m^{3}$ and then right at 60 kPa; III first right at 20 kPa and then up at 50 $c m^{3}$ . Which statements are correct?

Options:(select one or more)

Answer:

A, B, C

Solution:

$Δ V = 30 cm^{3} = 3 \times 1 0^{- 5} m^{3}$ . I: mean pressure 40 kPa gives $1.2$ J. II: 60 kPa gives $1.8$ J. III: 20 kPa gives $0.6$ J. D is wrong.
