MHT CET Physics question
A container with insulating walls is divided into two equal parts by a partition fitted with a valve. One part is filled with an ideal gas at a pressure and temperature , whereas the other part is completely evacuated. If the valve is suddenly opened, the pressure and temperature of the gas will be
Answer: (A)
Solution
Free expansion into vacuum in an insulated container does no work and exchanges no heat, so the internal energy and hence of an ideal gas
