Assertion: Increasing pressure on pure water decreases its freezing point. Reason: Density of water is maximum at 4° C.

Freezing point of water is the temperature at which water converts from a liquid-state to solid-state. It decreases with an increase in pressure due to high compact forces on the system. And the density of water is maximum at 3 4 1 gm c cm . Both assertion and reason are true, but the reason is not the correct explanation of assertion.
