NEETPhysicsThermodynamics
Answer the following by appropriately matching the lists based on the information given in the paragraph. In a thermodynamics process on an ideal monatomic gas, the infinitesimal heat absorbed by the gas is given by T Δ X , where T is temperature of the system and Δ X is the infinitesimal change in a thermodynamic quantity X of the system. For a mole of monatomic ideal gas X = 3 2 R l n T T A + R l n V V A . Here, R
