Q. When water is heated from 0°C to 10°C, what will happen to its volume? Answer:
first decreases and then increases
Notes: Initially at start of heating from 0°C to 4°C there will be a contraction as a result of which volume decreases. On further heating beyond 4°C to 10°C the molecules gain kinetic energy and start moving more randomly. Thus, intermolecular distance increases as a result of which its volume increases.
