A) the pressure decreases B) the kinetic energy of the molecules remains the sameC) the kinetic energy of the molecules decreasesD) the number of molecules of the gas increases

Answered by admin @ 29/08/2021

hey ,

⏩pressure is inversely proportional to the volume at constant temperature Hence a) is correct

⏩average kinetic energy of gas is directly proportional to Absolute Temperature and b) is correct

⏩expansion at constant temperature cannot change the number of molecules and D) is correct

Thanks!
