Question
During evaporation of water there is the simultaneous loss of:Question 10Select one:A.Liquid waterB.Mass of water and heatC.Mass of waterD.Heat
Solution
The correct answer is B. Mass of water and heat.
Here's why:
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. When evaporation occurs, the energy removed from the vaporized liquid will reduce the temperature of the liquid, resulting in evaporative cooling.
Step 1: The water molecules on the surface of the liquid gain energy from the surrounding environment. This energy can be from heat or the kinetic energy of other molecules.
Step 2: When these molecules gain enough energy, they can overcome the intermolecular forces that are holding them in the liquid and they escape into the air. This is the actual evaporation process.
Step 3: As the molecules leave the liquid, they take away energy with them. This results in a decrease in temperature of the remaining liquid, as energy (in the form of heat) is lost.
Step 4: The mass of the liquid also decreases as molecules leave the liquid phase and enter the gas phase.
So, during evaporation, there is a loss of both the mass of water (as it turns into a gas) and heat (as energy is taken away from the liquid).
