Gay-Lussac’s law is a relationship between P and T.
It states that the pressure of a given amount of gas is directly proportional to its temperature on the kelvin scale when the volume is held constant.
It is assumed that the volume remains constant.
Mathematically:
P ∝ T or P = constant × T or P = k × T; k = constant
∝ means directly proportional
----------
If the temperature increases, according to this formula: P = constant × T, the pressure will increase too.
Answer: The pressure would increase
