Question

Volume of the given mass of gas is directly proportional to the pressure at a constant temperature.

• A. True
• B. False

Answer 1

The correct option is B False

• Volume of the given mass of gas is inversely proportional to the pressure at a constant temperature.
• This is Boyle's law, which state that volume of the given mass of a gas is inversely proportional to the pressure at a constant temperature.
• If a given mass of gas occupies a volume V at pressure P and temperature T, then the equation becomes

V ∝ $\frac{1}{\mathrm{P}}$ or V= K $\frac{1}{\mathrm{P}}$ or PV= K (K is the proportionality constant).

Hence Volume of the given mass of gas is directly proportional to the pressure at a constant temperature is a false statement.
