Question

What happens when pressure is constant ?

Answer 1

1. Ideal gas equation is given by-,
   $PV=nRT$
   where, P is pressure of the gas, V is volume of the gas, n is the number of moles of the gas, R is the gas constant, T is the temperature
2. According to ideal gas equation, if pressure is constant, then for a fixed gas the volume occupied by that gas is directly proportional to the temperature.
3. This law is known as Charle's law.
   $$\begin{gathered} \mathrm{V}\mathrm{\alpha }\mathrm{T} \\ \frac{{\mathrm{V}}_1}{{\mathrm{T}}_1}=\frac{{\mathrm{V}}_2}{{\mathrm{T}}_2} \end{gathered}$$
4. Where, V is the volume and T is the temperature.
