hot is hot cool air is cold
Hot air from a radiator reaches the other side of a room by convection current. Convection current is when hot water/ air rises, hot water/ air cools, cool water/ air sinks, cool water/ air warms and then the cycle starts over.
Condensation of the cool air on the hot glass.
If the liquid is not very hot, stand it in a container of water. Leave it in a cool place. Direct cool air onto it.
A rubber ball rises up in the water because it is full of a substance (rubber) that is lighter than the same volume of water. A hot air balloon rises up into the cool air because it is full of a substance (hot air) that is lighter than the same volume of cool air. The hot air balloon floats in cool air, just like the rubber ball floats in water.
No. Dense air is cool air.
Hot air rises.
Swamp coolers depend on evaporation of water to cool the air. The hotter the temperature and drier the air, the better they are able to cool.
Because hot air rises and cool air sinks. the reason why is because hot air is less dense than cool air so the cooler air will sink
well......an industry will use water to cool materials because it helps prevent any hot air to come it....
== == It sure doesn't hurt, just make sure your mouth is a little closed, almost like whistling, to make sure that you're blowing cool air not hot air.
2004 grand marquis blowing cool air cant get hot air why?
