Solution
The correct option is D increase in temperature and increase in pressure The adiabatic condition is given by the relation between pressure volume and temperature volume as:
PVγ= constant and TVγ−1= constant where, γ=CpCv is ratio of the specific heats These relations suggest that an decrease in volume is associated with increase in temperature and pressure.
