Statement-1: The heat absorbed during the adiabatic expansion of an a ideal gas against vacuum is zero. Statement-2:The volume occupied by an ideal gas is zero.
The entropy change in the isothermal reversible expansion of 2 moles of an ideal gas from 10 to 100 L at 300 K is
Assertion : In free expansion of an ideal gas, the entropy increases. Reason : Entropy increases in all natural processes.
The entropy of a gas increases on its expansion . Why?
How does entropy changes with a. Increase in temperature b. Decrease in pressure?
Statement -1 : When temperature is incrteased, viscosity of the gas decreases. Statement -2 : With the increase in temperature, the gas becomes lighter.
