Final answer:
When 2 kilograms of water are in the gas phase, there will be no water in the liquid phase. The gas phase, also known as water vapor, occurs when water reaches its boiling point and changes from a liquid to a gas.
Step-by-step explanation:
When 2 kilograms of water are in the gas phase, there will be no water in the liquid phase. The gas phase, also known as water vapor, occurs when water reaches its boiling point and changes from a liquid to a gas.
Conversely, when water vapor condenses, it changes from a gas to a liquid. So, if you have 2 kilograms of water in the gas phase, it means that all of the water is in the form of water vapor and not in the liquid phase.
