The pressure inside a balloon is proportional to the square of its diameter. It contains 2 kg of water at 150 kPa with 85% quality. The balloon and water are now heated so that a final pressure of 600 kPa is reached. The process undergone by the water is given by p-v equation as:
1
\(P{V^{ - \frac{2}{3}}} = \rm{constant}\)
2
\(P{V^{ \frac{2}{3}}} = \rm{constant}\)
3
\(P{V^{ \frac{2}{5}}} = \rm{constant}\)
4
\(P{V^{ - \frac{2}{5}}} = \rm{constant}\)
