Physics - Heat & Thermo Question with Solution | TestHub

Water expands by about 9\% on freezing (ice density $\approx 920\mathrm{kg}{m}^{-3}$ vs 1000). Freezing in a closed pipe, especially when an ice plug traps the remaining water, builds enormous pressure that exceeds the pipe's strength. Both are true. The Reason gives the physical cause of the Assertion. Correct option: (A).
