A mixture of ideal gas containing 5 moles of monatomic gas and 1 mole of rigid diatomic gas is initially at pressure P₀, volume V₀, and temperature T₀. If the gas mixture is adiabatically compressed to a volume $${{{V_0}} \over 4}$$, then the correct statement(s) is/are

(Given, 2^1.2 = 2.3; 2^3.2 = 9.2; R is a gas constant)

The final pressure of the gas mixture after compression is in between 9P₀ and 10P₀

The average kinetic energy of the gas mixture after compression is in between 18RT₀ and 19RT₀

Adiabatic constant of the gas mixture is 1.6

The work |W| done during the process is 13RT₀

JEE Advanced 2019 Paper 1 Offline Physics - Heat and Thermodynamics Question 41 English

Work done in this thermodynamic cycle (1$$ \to $$2$$ \to $$3$$ \to $$4$$ \to $$1) is $$\left| W \right| = {1 \over 2}R{T_0}$$.

The ratio of heat transfer during processes 1$$ \to $$2 and 2$$ \to $$3 is $$\left| {{{{Q_{1 \to 2}}} \over {{Q_{2 \to 3}}}}} \right| = {5 \over 3}$$

The above thermodynamic cycle exhibits only isochoric and adiabatic processes.

The ratio of heat transfer during processes 1$$ \to $$2 and 3$$ \to $$4 is $$\left| {{{{Q_{1 \to 2}}} \over {{Q_{3 \to 4}}}}} \right| = {1 \over 2}$$

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

JEE Advanced 2015 Paper 2 Offline Physics - Heat and Thermodynamics Question 35 English

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 $${17 \over 6}{P_1}{V_1}$$
