Isn't cold water already cold? I would say cold water gets cold first. I've heard that hot water freezes faster than cold water.
When hot water is mixed with cold water, the overall temperature of the mixture will be between the initial temperatures of the hot and cold water. The hot water will transfer heat to the cold water, resulting in a gradual temperature equilibrium.
When hot water is poured into cold water, the hot water will transfer its heat energy to the cold water, causing the overall temperature of the mixture to increase. Eventually, the hot and cold water will reach a thermal equilibrium where they have the same temperature throughout the mixture.
Ammonia is soluble in both hot and cold water, with a higher solubility in cold water.
Warm water is lighter than cold water because the molecules are more active in warmer water and evaporation is taking place more quickly than in cold water.
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.
warm it up every time it gets cold
It gets numb.
it was the cold water.
cold
hot
it gets its water from the rain Evan though it could be hot or cold.
Hot water pipe rust first as compared to the cold water pipe for the same chemical composition of the water.
When you flush your toilet, cold water is used, this diverts cold water from the sinks and showers, resulting in diminished cold water flow momentarily at the sinks and showers, so, less cold mixed with hot, = hotter sinks and showers.
hot
the termometre gets warmer
On single handle shower valves, designed to let cold water first and turn handle farther to mix hot water to desired setting. If hot water turned on first, possibility of getting scalded. If seperate hot/cold handles for shower, shower valve needs work.
Hot water may feel cold when it first comes out of the tap because the pipes carrying the water may be cold, causing the water temperature to drop before reaching the faucet.
