Question

a gas expands from p1 to pressure p2 (p2=p1/10) if the process of expansion is isothermal the volume at the end of expansion is .55m3

Answer 1

Since, Gas expands against constant external pressure of 2 ATM until its volume has increased from 6 L to 10 L.

Gas absorbs 500 J of heat from the surroundings during this process.

Calculate the energy change of the gas ΔU.

As gas expand adiabatically between the same initial and final states thus it calculates the work done on the gas.
