There are three sets of sketches below, showing the same pure molecular compound (water, molecular formula H₂O) 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 H₂O: 0.0 °C boiling point of H₂O: 100.0 °C A B (Choose one) (Choose one) 79. °C 1 ² 3 4 5 -16. °C (Choose one) X 17 ii 215. °C S
