If a gas with P = Po and V = Vo expands isothermally to P = 3Po then the volume becomes:
Correct answer: C. Vo/3
- A. 3Vo
- B. 2Vo
- C. Vo/3
- D. Vo/2
Explanation
By boyle's law; V∝1/PIf V=Vo and P=3Po then Vo /3 ∝1/3PoSince pressure and volume of a gas are inversely proportional,therefore if pressure rises by three times,the volume must fall to one third of its value.Hence V becomes Vo/3.C is the correct option.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
