Two kg of steam is contained in a piston-cylinder arrangement. The 20-mm-dia, 48-kg piston is allowed to rise with no friction until the temperature reaches 250°C. The final volume is nearest:
A) 0.422 m3
B) 0.388 m3
C) 0.302 m3
D) 0.284 m3
D) 0.284 m3
The pressure in the cylinder is 
At 250°C and 1.6 MPa, V = mv = 2×0.1418 = 0.2836 m3
