Step-by-step explanation:
Convection is defined as a process in which movement of particles of fluid is due to heat and less dense fluid rises and more denser (colder) material sink because of the influence of gravity, this results in transfer of heat.
Thus, we can conclude that the statements which accurately describe convection in water are as follows.
- Cold water sinks because it is more dense than warm water.
- Warm water rises because it is less dense than cold water.
