Why does Hot water extinguishes fire more effectively than cold water?
Hot Water extinguishes more effectively than cold water as it has a higher specific heat capacity than cold water.
What is the fastest way to remove heat from concrete?
Cold water
If hot water is added to cold water and the cold water heats up what is this process called?
The process is simply heat transfer from hotter water to colder water.
Why does a drink get colder with ice?
The water has more heat than ice ... the water looses the heat to the ice the ice melts to become water .. but not warm water .. cold water that also looses heat to the warm water till equilibrium is reached and a final cool temperature is maintained .. but then the air around the water adds heat to the cold water till they all reach equilibrium and the water is warm again ..
Does hot water freezes faster than cold water when kept under insulation?
The question is unclear - Which, if not both, temperature waters are insulated? Do the insulations, if both, vary? I am assuming we are purely talking liquids freezing here rather than including vapour. Cooling water down relies on the transmission of heat away from it so, assuming similar insulation: Other combinations - No, cold would freeze first. In similar conditions, hot water still has to loose the heat energy and become cold in addition to the time to chill from cold to frozen. Hot uninsulated vs Cold insulated - Possibly, depending on the insulation. If the energy loss were reduced for the cold water then if could be the case that hot water would freeze first. :-)
Describe how the body can loose heat in conduction convection and radiation?
you are swimming in ice cold water and losing heat. How does heat leave your body?
Describe the method of heat transfer involved when you mix hot water with cold water to make lukewarm water?
conduction and convection
What is the source of darkness and cold since the sun is the source of heat and light?
We're modestly familiar with the source of heat and light. And we know that heat and light both exist and are real. Cold and darkness do not exist. They merely describe the lack of heat and light, respectively.
Describe how the heat from the stove gets to the water in the pot?
As the stove heats up the pot, heat is transferred from the pot to the water through conduction. Within the pot, heat is transferred through convection from the hot water molecules to the cold ones.
Why does cold water heat up when hot water is added?
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 Hot water extinguishes fire more effectively than cold water?
Hot Water extinguishes more effectively than cold water as it has a higher specific heat capacity than cold water.
Why does heat dissolve in water?
Hot water merges with the cold water, and any heat is dissipated.
When you dip your hand in cold water you feel it cold. Can you name the mode of heat transfer and its direction?
This type of heat transfer is called conduction. The transfer is from the warm hand to cool water.
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 convection transfer heat?
Think of a pot of boiling water. The burner makes the heat, the heat rises, and the cold water replaces it, then the cold water gets hotter and rises. It's a cycle
