Question

What is Regnault’s Law?

Answer 1

1. According to Regnault's law at constant pressure the specific heat of gas is the same.
2. Regnault's law is also called Gay lusac's law.
3. This states that pressure exerted by a gas is directly proportional to the absolute temperature.
4. It can be mathematically represented as follows:$\mathrm{P}\propto \mathrm{T}$; $\frac{\mathrm{P}}{\mathrm{T}}=\mathrm{K}$; where P is the pressure and T is the absolute temperature, and K is the constant of proportionality.
5. Example: A pressure cooker is heated to certain temperature will increases the pressure inside the cooker which helps food to cook faster
