Cold water heats up when warm water is added because of the second law of thermodynamics. Basically, the heat energy of the hot water is distributed evenly to the colder water, raising its temperature until both are in equilibrium with each other.

When hot water is added to cold water, heat energy is transferred from the hot water to the cold water through a process called conduction. This causes the temperature of the cold water to increase as it absorbs the heat energy from the hot water. The two temperatures eventually reach an equilibrium where they are at the same temperature.

Why does cold water warm up when added to hot water?

Heat energy is transferred from the hot water to the cold.


Does water always turn into ice when its cold?

no. Ice can evaporate into a gas by melting into water and turning into a gas when more heat is added. Gas can be hot or cold


Can hot water added into the inlet cold water?

no


What direction will heat flow if cold water is added to a hot pan?

Heat will flow from the hot pan to the cold water, as heat always flows from higher temperature to lower temperature in an attempt to reach thermal equilibrium.


What type of heat transfer occurs when hot water flows through cold water?

Convection is the type of heat transfer that occurs when hot water flows through cold water. As the hot water moves through the cold water, it transfers heat energy to the surrounding cold water, causing it to warm up. This results in a transfer of heat through the movement of the fluids.


Why does heat dissolve in water?

Hot water merges with the cold water, and any heat is dissipated.


When you added hot water to cold water what process occured?

condensation


If you heat the water at 7 degree Celsius when you insert your finger into the water will the water be hot or cold?

cold


Does hot water have a lower specific heat than cold water?

No


Will cold water extinguish a fire faster than hot water?

Yes it will. This is because cold water has less heat than hot water and therefore can absorb more heat when put on the fire.


Why does hot water evaperate faster then cold water?

Because water evaporates from heat energy which hot water has more of.


What happens if you mix hot water with 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.
