Water is H2O no matter what temperature it is, hot or cold. H2O Cold
Hot water freezes faster than cold water. Water molecules are composed of one oxygen atom bonded to two hydrogen molecules. When water molecules come in close contact, a natural repulsion between the molecules to stretch and store energy. As the water heats, the hydrogen bonds stretch as the water gets less dense and the molecules move further apart.
Metals like copper, silver, and gold do not react with cold water because they are less reactive. This is due to their position in the reactivity series, where they do not displace hydrogen from water.
A thermos keeps hot drinks hot and cold drinks cold by using a vacuum layer between two walls of the container. This vacuum layer prevents heat transfer by conduction, convection, and radiation. The result is that hot drinks stay hot because heat loss is minimized, and cold drinks stay cold because heat gain is minimized.
Lead oxide is yellow when hot and reddish-brown when cold.
Hot air, hydrogen or helium are lighter than cold air.

Air moves from hot to cold.
Heat flows from hot to cold.

hot, if cold, there is a posibility of a cold!
hot to cold is heat transfer
is it hot or cold tomorrow
do clouds get hot or cold
No, hot and cold are adjectives.
