A cylinder has a piston at temperature of $30 ° C$ . There is all round clearance of $0.08 mm$ between the piston and cylinder wall if internal diameter of the cylinder is $15 cm$ . What is the temperature at which piston will fit into the cylinder exactly? $(α_{p} = 1.6 \times 10^{- 5} / {}^{\circ}C$ and $α_{c} = 1.2 \times 10^{- 5} / {}^{\circ}C)$
