An ideal monoatomic gas is confined in a horizontal cylinder by a spring loaded piston (as shown in the figure). Initially the gas is at temperature T₁, pressure P₁ and volume V₁ and the spring is in its relaxed state. The gas is then heated very slowly to temperature T₂, pressure P₂ and volume V₂. During this process the piston moves out by a distance x.

Ignoring the friction between the piston and the cylinder, the correct statements is/are

If V₂ = 2V₁ and T₂ = 3T_l, then the energy stored in the spring is $${1 \over 4}{P_1}{V_1}$$

If V₂ = 2V₁ and T₂ = 3T₁, then the change in internal energy is $$3{P_1}{V_1}$$

If V₂ = 3V₁ and T₂ = 4T₁, then the work done by the gas is $${7 \over 3}{P_1}{V_1}$$

If V₂ = 3V₁ and T₂ = 4T₁, then the heat supplied to the gas is $${17 \over 6}{P_1}{V_1}$$

The figure below shows the variation of specific heat capacity (C) of a solid as a function of temperature (T). The temperature is increased continuously from 0 to 500 K at a constant rate. Ignoring any volume change, the following statement(s) is(are) correct to a reasonable approximation.

JEE Advanced 2013 Paper 2 Offline Physics - Heat and Thermodynamics Question 28 English

The rate at which heat is absorbed in the range 0-100 K varies linearly with temperature T.

Heat absorbed in increasing the temperature from 0-100 K is less than the heat required for increasing the temperature from 400-500 K.

There is no change in the rate of heat absorption in the range 400-500 K.

The rate of heat absorption increases in the range 200-300 K.
