To determine the variables involved in Gay-Lussac's Law, let's first understand what Gay-Lussac's Law states.

Gay-Lussac's Law describes the relationship between pressure and temperature for a fixed amount of gas at constant volume. The law indicates that, for a given mass and constant volume of gas, the pressure exerted by the gas is directly proportional to its absolute temperature.

In detail, when the temperature of a gas increases, its pressure also increases if the volume remains constant, and vice versa. Mathematically, Gay-Lussac's Law can be represented as:
[tex]\[ \frac{P_1}{T_1} = \frac{P_2}{T_2} \][/tex]
where:
- [tex]\( P_1 \)[/tex] and [tex]\( P_2 \)[/tex] are the initial and final pressures respectively,
- [tex]\( T_1 \)[/tex] and [tex]\( T_2 \)[/tex] are the initial and final absolute temperatures respectively.

Based on this understanding, the primary variables in Gay-Lussac's Law are pressure and temperature.

So, the variables in Gay-Lussac's Law that change are pressure and temperature.
