A U tube made of heat insulating material is shown in figure One limb is closed by a non conducting cork the temperature is To 300 K a 10 J heat is required to be given by the coil so that the air rises to a temperature T 510 K The thermal expansion of mercury is negligible Then the value of a choose nearest integer value of a Neglect the heat flow through the mercury Take Area of the tube as 0 1 m P 75 cm of Hg atm 25 R and density of mercury PH 13 6 x 10 kg m 23 Insulating massless piston h 10 cm Hg
