Transcribed Image Text:
Consider the piston-cylinder arrangement sketched
in the figure. The mass of water is 2 kg and it is
initially at V₁ =0.02 m³, T₁ = 50 °C. The water is
heated and the piston; which is initially resting on
stops; starts to move only when the pressure inside
the cylinder is 100 kPa. The heating continues until
it reaches a final state of 200 °C. Show all your
work clearly.
