Verified answer
When an Ideal gas is expanded into vacuum, it does no work. (W =0) Hence, no change in the internal energy and thus in the temperature of the gas. This means the q = 0, change in internal energy and enthalpy are also zero. Hence, Option (4) is correct.
Answer:
the answer is all of these
Explanation:
If an ideal gas or perfect gas
expands into vacuum, it does
no work
i.e, work done = 0
& this process is considered to
be an adiabatic process,
where q=0
ΔU=0
Also, ΔH=ΔU+Workdone
ΔH=0+0
ΔH=0
