At constant temperature, Write the statement of law.

टिप्पणी लिखिए

उत्तर

Statement of Boyle’s law: For a fixed mass (number of moles ‘n’) of a gas at a constant temperature, the pressure (P) of the gas is inversely proportional to the volume (V) of the gas.
OR
At constant temperature, the pressure of a fixed amount (number of moles) of a gas varies inversely with its volume.
