Step-by-Step Solution
$K_H$ is Henry's law constant. It is a function of the nature of the gas as well as temperature. Different gases have different $K_H$ values at the same temperature. Furthermore, the value of $K_H$ increases with an increase in temperature, indicating that the solubility of gases decreases with increase in temperature.
