Answer:
Gay-Lussac’s law
Explanation:
Gay-Lussac’s law is one of the gas laws discovered and proposed by a French scientist called Joseph Gay Lussac (1778 - 1850). In this law, it is stated that the pressure (P) of a gas varies directly with the absolute temperature (T) at a constant volume.
That is;
: P ∝ T
: P/T = K
Where:
P = pressure exerted by the gas
T = absolute temperature of the gas
K = the constant.
Hence, according to this question, the law that states that "the pressure and absolute temperature of a fixed quantity of gas are directly proportional under constant volume conditions" is Gay-Lussac’s law.
