Answer:
The lower the surface tension, the better the water wets surfaces, and the faster it creeps into tiny spaces like those between the fibres in a cotton ball. ... Cotton balls sink faster in hot or soapy water because both wet the cotton fibres and replace the air trapped between them much faster than pure cold water.

Answer:
your answer is--
Explanation:
If the water is initially hot, cooled water at the bottom is denser than the hot water at the top, so no convection will occur and the bottom part will start freezing while the top is still warm. This effect, combined with the evaporation effect, may make hot water freeze faster than cold water in some cases
