Answer 2

Answer:(4) P/10

Explanation:Free expansion - expansion under vacuum at adiabatic conditions.

So in adiabatic process Q=0 and in vaccum W=0

So from first law of thermodynamics (FLOT)

Q=U+W

=>Delta U =Q-W

=>Delta U=0

n×Cv×deltaT=0

n and Cv can't be 0 so deltaT is 0 thus temperature is const

Therefore'from ideal gas equation PV=nRT

Thus, PV=Constant

P'=(PV)/V'

P'= (P×1.01)/10.1

P'=P/10

Hence 4th option is correct.
