PhysicsMediummultiple choice

A gas ( $γ = 1.4$ ) at 1 atm and 300 K in a thermally insulated 5 litre container is compressed to 1 litre. Which statements are correct?

Options:(select one or more)

Answer:

A, B, C

Solution:

Sudden: adiabatic, $P = 5^{1.4} = 9.52$ atm and $T = 300 \times 5^{0.4} = 571$ K. The container is insulated, so slow compression is also adiabatic and gives the same values. D assumes an isothermal slow compression, which insulation rules out.
