KMT is a well - known term in science referring to Kinetic Molecular Theory which describes the behavior of gases in terms of molecular motion.

Step1: Recall Dalton's law of partial pressures

According to Dalton's law, the total pressure ($P_{total}$) of a gas mixture is the sum of the partial pressures of its components. So $P_{total}=P_{H_2}+P_{N_2}+P_{H_2O}$.

Step2: Rearrange the formula to find $P_{H_2O}$

$P_{H_2O}=P_{total}-P_{H_2}-P_{N_2}$.

Step3: Substitute the given values

$P_{total} = 864$ mmHg, $P_{H_2}=220$ mmHg, $P_{N_2}=410$ mmHg. Then $P_{H_2O}=864 - 220-410$.
$P_{H_2O}=234$ mmHg.

Based on the kinetic - molecular theory and gas laws, an increase in temperature leads to an increase in the movement (velocity) of gas molecules, their kinetic energy, and also causes an increase in volume and pressure (assuming other factors are constant or under appropriate conditions).

B. Kinetic Molecular Theory
