Problem

A cylinder of mass 1 kg is given heat of 20,000 J at atmospheric pressure. If initially the temperature of cylinder is

20^\circ\text{C}

, find (Given that specific heat of cylinder =

400\ \text{J kg}^{-1}\,^\circ\text{C}^{-1}

, coefficient of volume expansion =

9 \times 10^{-5}\,^\circ\text{C}^{-1}

, atmospheric pressure =

10^5\ \text{N/m}^2

and density of cylinder =

9000\ \text{kg/m}^3

) (a) final temperature of the cylinder. (b) work done by the cylinder. (c) change in internal energy of the cylinder
