Water makes different pouring sounds depending on its temperature:

If you listen very closely, hot water and cold water sound slightly different when being poured. The heat changes the thickness, or viscosity, of the water, which changes the pitch of the sound it makes when it's poured. What we feel as heat comes from the molecules of the water moving faster. Cold water is thicker and therefore makes a slightly higher-pitched sound.
