The pressure and density of a diatomic gas (γ=7/5) change adiabatically from (P₁, p₁) to (P2, p₂). If p2/p1= 32,then P2/P1 should be

The thermodynamic process in which no work is done on or by the gas is

An ideal gas at 27 degree C is compressed adiabatically to (8/27) of its original volume. If ratio of specific heats, γ=5/3 then the rise in temperature of the gas is

A system is taken through a cyclic process represented by a circle as shown. The heat absorbed by the system is

A sample of a gas expands from volume ‘V1’ to ‘V₂’. The amount of work done by the gas is maximum when the expansion is

A thermodynamical system undergoes a cyclic process ACDEA as shown in figure. Work done by the system is

An ideal gas which is diatomic (γ= 7/5) 5 undergoes an adiabatic change. If the relation between temperature and volume is TV = constant, then the value of x is

A thermodynamic process in which total change in the internal energy of the system is zero is

In a thermodynamic system, ‘W’ represents the work done by the system and △U is the increase in internal energy, which of the following statements is TRUE?

In the P-V diagram shown, there are two adiabatic parts of the same gas intersecting two isothermals at T1 and T₂. The ratio (Vb/Va) is equal to
