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.
The porous jar help evaporation and evaporation is an endothermic process.
The Earthen jar is porous.
warmer
yes it is dangerous, becasue it will become warmer and then a exothermic reaction will happen hope this helped ;D
Steam is warmer because it's not freezing like ice.
As you might expect from the term "expansion", they get farther apart from each other - at least on average. They also tend to gain more vibrational energy, rotate faster (when able to) and move around faster in general.
Because it is in contact with something colder. When a warmer body is in contact with a cold body, the warmer one will give off heat to the cold one. This cools the warmer one and warms the cooler one.
The room won't immediately become warmer; however, when the curtains are closed, less heat will escape through the windows.
Warmer

Absorbed by them.
as air become warmer velocity of sound increases
move faster.
move faster.
C02 and lactic acid
The warm water currents in the ocean make the atmosphere warmer hence the climate of those regions become warmer.
You must have Mr. Williams.
Because the electrons in it are moving about. This is similar to what happens when you run about, you become 'hot'.
