4/3

2

5/3

3/2

Solution

3/2

According space to space question comma straight p proportional to space straight T cubed pV space equals nRT and space straight p proportional to space straight T cubed space straight p proportional to space left parenthesis pV right parenthesis cubed straight p squared straight V cubed space equals space constant pV to the power of 3 divided by 2 end exponent space equals space constant pV to the power of straight gamma space equals space constant space straight gamma space equals space 3 divided by 2
