Condensation of water vapour into water is influenced by which of the following factor/factors? 1. Volume of air 2. Humidity 3. Temperature. Select the answer using the code given below:

All three factors—volume of air, humidity, and temperature—influence the condensation of water vapour into water. Temperature is the most direct factor: when air cools to its dew point, water vapour condenses. Humidity (the amount of water vapour present in the air) determines how much vapour is available to condense; air with higher humidity reaches saturation more quickly. The volume of air affects condensation because when air expands (increased volume), it cools adiabatically, which can trigger condensation, and when compressed it warms. Hence all three factors play important roles in the condensation process.
