Final answer:
A saturated liquid vapor mixture of water is called condensate, with vaporization and condensation rates being equal in a closed system. Steam, on the other hand, refers to water vapor that is fully gaseous, normally at or above 100°C. The rate of evaporation is influenced by temperature, with higher temperatures increasing this rate.
Therefore , option 1) is correct.
Step-by-step explanation:
A saturated liquid vapor mixture of water is called condensate when it exists in a state where the liquid and vapor phases are in equilibrium. This situation is typically found in a closed system where the rates of vaporization (liquid changing to gas) and condensation (gas changing back to liquid) are equal.
In contrast, steam refers to water vapor that is above the boiling point of water, typically at 100°C and 1.00 atm where it exists as a gas without liquid present. At temperatures below the boiling point, such as 20.0°C, water can still evaporate, with molecules moving from the liquid phase to the gas phase without boiling.
The phenomenon where a liquid turns into a vapor below its boiling point is evaporation. Factors like temperature do affect the rate of evaporation; higher temperatures generally result in a higher rate of evaporation due to increased molecular energy. This can be contrasted with boiling water, where the water is being heated to its boiling point and transitioning to a gas phase throughout the volume of the liquid, not just at the surface.
Relative humidity is important in discussing the behavior of water in the atmosphere, as it measures the fraction of water vapor present in the air compared to the maximum amount of vapor the air can hold at that temperature.
