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

Breakdown of the Problem

We need to identify what occurs simultaneously during the evaporation of water from the given multiple-choice options.

Relevant Concepts

Evaporation is a process whereby liquid water transitions to vapor. During this process:

1. Liquid water is transformed into water vapor, thus losing a portion of the liquid state.
2. It involves the loss of heat energy; this heat is necessary for the transition from liquid to vapor.

Analysis and Detail

1. Loss of Liquid Water: As water evaporates, it converts to vapor, meaning that the remaining volume of liquid water decreases.
2. Loss of Mass of Water: With the transformation into vapor, the total mass of water in the system also decreases.
3. Loss of Heat: The heat absorbed during evaporation is referred to as latent heat. Water requires energy for the phase change, which leads to a decrease in thermal energy in the surrounding environment.

Verify and Summarize

From the analysis, it can be confirmed that during evaporation, both liquid water and heat are lost simultaneously. Hence, the most comprehensive option includes both mass (due to the transformation to vapor) and heat (energy required for the phase change).

Final Answer

B. Mass of water and heat
