When boiling water is allowed to run off a tap onto a hard surface, it makes a sound different from that made by cold water on the same surface. More hollow...I just can't place the description of the sound but it is different..Why??

Brownian movement, viscosity, cohesion, etc are changed.
Brownian Movement: Atoms are always bombarding against each other. In Liquids like water they bombard rather slowly. When water is heated, the steamed up atoms are more excited and bombard even quicker, making way to more bombardments as compared to the colder ones. Thus the sound of pouring changes. Brownian movement also gives way to change in the viscosity and cohesion.

Many properties of water change when its temperature changes, such as the viscosity, cohesion and density. These will influence how the water shapes on impact and forms spats, drops and bubbles. Sound is also conducted differently by water with different properties.

I am not good at physics, but I think it's because of the density of water, it is more dense when it's cold
