State Charles’ law and give its formula.

1.	State Charles’ law and give its formula.
Answer» Charles’ law: At constant pressure, volume of a fixed mass of gas is directly proportional to its absolute temperature. Mathematically, V ∝ T … ( at constant pressure) ∴ V = kT where k is constant of proportionality ∴ \(\frac{V}{T}\) = k = constant For two gases, \(\frac{V_1}{T_1}=\frac{V_2}{T_2}\) = constant.

Answer»

Charles’ law:

At constant pressure, volume of a fixed mass of gas is directly proportional to its absolute temperature.

Mathematically,

V ∝ T … ( at constant pressure)

∴ V = kT

where k is constant of proportionality

∴ \(\frac{V}{T}\) = k = constant

For two gases, \(\frac{V_1}{T_1}=\frac{V_2}{T_2}\) = constant.
