Question

A quantity of air is taken from state a to state b along a path that is a straight line in the pV-diagram (Figure 1) .

Part A

In this process, does the temperature of the gas increase, decrease, or stay the same?

Part B

Explain

500 words max

temperature increases , temperature decreases, temperature stays the same

Part B

Explain

500 words max

Temperature increases.

From ideal gas equation:, The ratio of final temperature to inital temperature is:

PbVb/PaVa

From the diagram it is clear that he product pV increases and hence there is a temperature increase
