What is the chemical formula of cold water?
Water is H2O no matter what temperature it is, hot or cold. H2O Cold
Does hot water or cold water evaporate faster?
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.
What metals don't react with cold water?
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.
Why does thermos keep hot drinks hot and cold drinks cold?
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.
Will there be a reaction between zinc and water?
Zinc reacts with steam to form Zinc oxide(yellow when hot and white when cold) and hydrogen. Zn+H2O=ZnO +H2

Is jello better hot or cold?
hot, if cold, there is a posibility of a cold!
Is H20 stand for hot water and C20 stand for cold water?
No, H2O is the chemical formula for water, indicating that each molecule consists of two hydrogen atoms and one oxygen atom. C2O does not represent cold water; instead, there is no standard chemical formula for cold water. The temperature of water (hot or cold) is not indicated by its chemical formula.
Is 'hot' or 'cold' a verb?
No, hot and cold are adjectives.
