Explanation:

The dew point of a gas-vapour mixture refers to the temperature at which the mixture becomes saturated with water vapor and starts to condense into liquid water.

Effect of Temperature:
- As the temperature of the gas-vapour mixture rises, the dew point of the mixture decreases. This is because warmer air can hold more water vapor before reaching saturation, so the temperature increase lowers the relative humidity of the mixture.

Effect of Pressure:
- The dew point of a gas-vapour mixture decreases with a decrease in pressure. This is because lower pressure reduces the ability of the air to hold water vapor, leading to an earlier saturation point and a lower dew point.

Therefore, option 'C' is the correct answer as the dew point of a gas-vapour mixture decreases with a decrease in pressure.
