Gas Law III - The Pressure Law

(Also known as Gay-Lussac’s Law)

At a constant volume, experiments show that the pressure and absolute temperature of a gas are directly proportional.

$$\LARGE{p \propto T}$$

Where,

$p$ - pressure of the gas

$T$ - temperature of the gas

Using this,

$$\LARGE{\frac{p}{T} = constant}$$

Starter Questions

$Q1$. A gas is held at constant volume. Initially it exerts a pressure of $100Pa$ at a temperature of $35K$. The temperature is increased until the pressure exterted by the gas is $1000Pa$. Find the final temperature of the gas.

$Q2$. A gas is held at constant volume. Initially it exerts a pressure of $3000Pa$ at a temperature of $100^{\circ}C$. The pressure is increased until the temperature of the gas is $2000^{\circ}$. Find the final pressure exerted by the gas.
