Q139 / 150 · MHT CET 2026 (13 April Shift 1) · Physics
According to Boyle's law, the product PV remains constant. The SI unit of PV is same as that of
- Amomentum
- Correct answerBenergy
- Cforce
- Dimpulse
Solution
Pressure $P = \dfrac{\text{Force}}{\text{Area}}$
SI unit of $P = \text{N m}^{-2}$
SI unit of $V = \text{m}^3$
SI unit of $PV = \text{N m}^{-2} \times \text{m}^3 = \text{N m} = \text{Joule}$
Joule is the SI unit of energy.
Answer: energy
SI unit of $P = \text{N m}^{-2}$
SI unit of $V = \text{m}^3$
SI unit of $PV = \text{N m}^{-2} \times \text{m}^3 = \text{N m} = \text{Joule}$
Joule is the SI unit of energy.
Answer: energy
Hence, the correct answer is option: 'B'.
