There are three sets of sketches below, showing the same pure molecular compound (water, molecular formula $\mathrm{H}_{2} \mathrm{O}$ ) at three different temperatures. The sketches are drawn as if a sample of water were under a microscope so powerful that individual atoms could be seen. Only one sketch in each set is correct. Use the slider to choose the correct sketch in each set. You may need the following information: melting point of $\mathrm{H}_{2} \mathrm{O}: \quad 0.0^{\circ} \mathrm{C}$ boiling point of $\mathrm{H}_{2} \mathrm{O}: 100.0^{\circ} \mathrm{C}$

Solution

Solution Steps

Step 1: Analyze the Problem

We are asked to identify the correct sketch of water (H₂O) at three different temperatures for sets A, B, and C. We are given the melting point (0.0 °C) and boiling point (100.0 °C) of water. The slider below each set allows us to select a temperature. Each image within a set depicts water at a different temperature and phase (solid, liquid, or gas).

Step 2: Set A

No temperature is specified for Set A, so we cannot determine the correct sketch without more information.

Step 3: Set B

The slider for Set B indicates a temperature of -1 °C. This is below the melting point of water, so water would be in its solid phase (ice). In the solid phase, water molecules are arranged in a fixed, ordered structure.
