Thermodynamic Processes

If the pressure of an ideal gas is decreased by 10%10\% isothermally, then its volume will

Show answer and solution

Answer: (d)

  1. Isothermal: PVPV = constant.
  2. P′=0.9P⇒V′=V0.9=1.111VP' = 0.9P \Rightarrow V' = \frac{V}{0.9} = 1.111V
  3. Increase =11.1%= 11.1\%
  4. So the answer is (d) increase by 11.1%11.1\%.
