Due to pressure the gas expands and gives heat

Hey friend ✌
Here is u r Ans ⤵️⤵️⤵️
❄The internal energy of a real gas depends on both temperatureand pressure.
So, if U remains constant and pressure changes, the temperature must change.
❄In the idealgas limit of very low pressures, thepressure dependence of real gasesweakens and approaches zero.
❄The enclosure is insulated so there is no heat exchange.
The first law tells us therefore that the internal energy is constant ( ). For
an ideal gas, the internal energy is a function of temperature only so that the temperature of the gas before the free expansion and after the expansion has been completed is the same.
