Question

Temperature remaining constant, the pressure of a gas with increase in volume.

• A. decreases
• B. remains constant
• C. fluctuates
• D. increases

Answer 1

The correct option is A decreases

As per Boyle's law, temperature remaining constant, the volume (V) of a gas is inversely proportional to pressure (P).

i.e V α $\frac{1}{P}$ or $PV$ = constant.

Thus, if the volume increases, the pressure of the gas decreases.
