Question 9 of 10Which of the following is described by the equation H2O(l) + heat H2O(g)?A.MeltingB.EvaporatingC.FreezingD.Condensing

Break Down the Problem

1. Identify the equation: $\text{H}_2\text{O}(l) + \text{heat} \rightarrow \text{H}_2\text{O}(g)$
2. Determine what process is taking place based on the states of water involved.

Relevant Concepts

• States of Matter: The states of water involved are liquid (l) and gas (g).
• Heat Absorption: The addition of heat usually indicates a phase change from a lower energy state to a higher energy state.

Analysis and Detail

1. Identifying States: Water in liquid form is represented by $\text{H}_2\text{O}(l)$ and water vapor is represented by $\text{H}_2\text{O}(g)$.
2. Phase Change: The equation indicates that liquid water absorbs heat and transforms into gaseous water. This process is known as evaporation.

Verify and Summarize

• The addition of heat leads to the conversion from liquid to gas, which confirms that the correct answer reflects the evaporation process.

Final Answer

The correct answer is B. Evaporating.
