**Gay-Lussac's law** states that the **absolute** temperature and pressure of a fixed amount of an ideal gas are directly proportional to each other at **constant volume**.
$$P\propto T$$
The **combined gas law** is derived from the three laws above:
$$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{V_2}$$
**Dalton's law of partial pressures** states that the pressure of a mixture of gases is equal to the sum of the pressures of each gas. As pressure is directly proportional to the number of particles in the gas:
$$
P_T = \Sigma P \\
P\propto n \\
\frac{n_1}{n_T}P_T=P_1
$$
