Match List-I with List-II (where symbols have their usual meaning). List-I (Type of processes) List-II (Feature)A. Adiabatic I. Pressure constantB. Isothermal II. W = −ΔUC. Isobaric III. W = QD. Isochoric IV. Volume constant Choose the correct answer

Assertion : We can not change the temperature of a body without giving (or taking) heat to (or from) it.. Reason : According to principle of conservation of energy, total energy of a system should remains conserved.

In gases the particles are free to move about randomly moving in straight line between any two successive collisions. The velocity of particles in a gas is stated under different names and different conditions in column I and its values are given in

A monoatomic gas having γ = is stored in a thermally insulated container and the gas is suddenly compressed to th of its initial volume. The ratio of final pressure and initial pressure is : ( γ is the ratio of specific heats of the gas at constant p

Assertion (A): Two cylinders contain same amount of ideal monatomic gas. Same heat given. Temperature rise in cylinder A (free piston) is T₀, then in B (fixed piston) is (5/3)T.
