Question

At constant temperature, the product of pressure and volume of a given amount of a gas is constant. This is:

• A. Gay-Lussac's law
• B. Charles' law
• C. Boyle's law
• D. Pressure law

Answer 1

The correct option is C Boyle's law

At constant temperature, the product of pressure and volume of a given amount of a gas is constant. This is known as Boyle's law.
The pressure (P) of a given mass of a gas varies inversely as its volume (V) at a constant temperature.
$P\propto \frac{1}{V}$
$PV=$ constant.
