प्रश्न
If the piston of a container is pushed fast inward. Will the ideal gas equation be valid in the intermediate stage? If not, why?

उत्तर
When the piston is compressed so quickly that there is no time to exchange heat to the surrounding, the temperature of the gas increases rapidly. In this intermediate stage, the ideal gas equation is not valid. Because this equation can relate the pressure, volume and temperature of the thermodynamic system at equilibrium.
