What two phase changes occur between vapor water and liquid water, and at what temperature does each phase change take place?
Answer (3)
Water freezes at 32 degrees so after that it will melt and turn into liquid water, water boils at 112 degrees which will cause steam
Vaporization and condensation are the two phase changes between vapor water and liquid water. Vaporization, or boiling, occurs at 100°C and transforms liquid water into gas. Condensation happens at the same temperature but reverses the process, turning gas back into liquid.
The two phase changes that occur between vapor water and liquid water are vaporization (also known as boiling) and condensation. Vaporization is the process where liquid water turns into gas, and condensation is when vapor converts back into liquid water.
The temperature at which vaporization occurs is 100°C (or 212°F), which is also the boiling point of water at standard atmospheric pressure. Condensation occurs at the same temperature, but it's the process of gas changing back to the liquid phase.
Vaporization requires heat. The specific amount of heat required to convert one gram of liquid into gas at its boiling point is called the latent heat of vaporization. Conversely, during condensation, heat is released as the gas transitions back into a liquid.
Condensation takes place when the water vapor comes into contact with a cooler surface or as the air is cooled to its dew point and can't hold as much water vapor, leading to the formation of liquid water droplets.
The two phase changes between vapor water and liquid water are vaporization, occurring at 100°C when liquid turns to gas, and condensation, also at 100°C when gas turns back to liquid. Both processes involve heat exchange; vaporization absorbs heat, and condensation releases heat. These phase changes are crucial in understanding the water cycle and energy transfer in nature.
