It doesn't, it is room temperature minus visible light heat unless in a conductive / heat absorbing container.

Why water kept in earthen pot remains cold?
The earhern pots used for keeping water cool in summer have small pores in it.water seeps in these pores and evaporates.as evaporation causes cooling, earthen pots remain cool.
Which will warm faster a black pot of cold water or a silvered pot cold water?
the silvered pot will warm faster because it reflects more ligh than the black pot.
Why water kept in earthern pots becomes cold after sometime?
Water stored in clay jar become cold because of water moves from the inner surface to the outer surface of the clay jar.
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.
How does water kept ina earthen pot become cool during summer?
By evaporation
What are examples of convection?
in a pot on the stove, cold water sinks to the bottom and hot water circulates on the top of the pot. (The colder water needs to become hot, so it sinks to the bottom. That's why you see movement in the pot of water.)
Why does water in a closed glass jar become warmer than water in closed earthen jar at the same dimension?
Provided the earthenware pot is UNGLAZED, the water inside the pot will seep through the pot making it damp on the outside. The dampness on the outside then evaporates and cools the pot and the water in it. (Lick your finger then blow on it gently and you will find your finger feels cold). However, a glass bottle is impervious to water, so the outside remains dry and there is no evaporation and the water in the bottle does not cool.
Is adding water to pot noodles a physical change?
This depends. Are the pot noodles dry at room temperature? Then not yet .Are the pot noodles in boiling water? Is the water you are adding from the cold water tap? Then, Yes, as boiling will stop until the new water is at boiling temperature.
How does the water kept in an earthen pot become cool during summer?
An earthen pot has small pores in its walls. When water is poured into it, some of it seeps through these pores to its outer surface. On reaching there, it evaporates.The heat required for evaporation is taken from the earthen pot and from the water in it. As a result, the water in an earthen pot gets cooled down.
How can you save a pot that has been on a stove on HI heat and had water in it but the water got boiled out?
When water evaporates it leaves a white residue that can sometimes be removed by soaking the pot in white vinegar. The vinegar removes water residue on lots of things.
HOW to make coffee?
Making good coffee takes ground coffee, good quality filters, cold water and of course, a coffee pot. For a drip pot, insert the filter in the basket, dump the coffee into the filter depending on how strong you want it to be, pour cold water into the top of the pot and turn it on.
How does convection transfer?
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
