Previous Question: A thin uniform cylindrical shell, closed at both ends, is partially filled with water. It is floating vertically in water in half-submerged state. If ï²c is the relative density of the material of the shell with respect to water, then the correct statement is that the shell is option (A) more than half filled if ï²c is less than 0.5 (B) more than half filled if ï²c is less than 1.0 (C) half filled if ï²c is less than 0.5 (D) less than half filled if ï²c is less than 0.5 Next Question: Two moles of ideal helium gas are in a rubber balloon at 30Â° C .The balloon is fully expandable and can be assumed to require no energy in its expansion. The temperature of the gas in the balloon is slowly changed to 35Â°C.The amount of heat required in raising the temperature is nearly (take R = 8.31 J/mol.K) option (A) 62J (B) 104 J (C) 124 J (D) 208 J
