How does air above a cooled surface move?
Air above a cold or cooled surface contracts and falls.
Is cooled a verb?

What happens to the rate of the evaporation of a liquid as the liquid is cooled?
When a liquid is cooled, the rate of evaporation slows down
Fifty grams of water cooled from 50 degrees to 10 degrees if the specific heat of wayer is 4.2 hoe much was released?
If fifty grams of water cooled from 50 degrees to 10 degrees, and the specific heat of water is 4.2, 135 kJ of heat was released.
How do you define melting point of gas as oxygen?
When cooled to below 54.36 K (-218.79 oC , -361.82 oF, oxygens melting point) it will become solid. That's what a 'melting point' is!
Why the liquid state became a solid state?
When it is cooled down below melting point.
How do use the word solidified in a sentence?
wax got solidified as soon as it cooled after melting
What are the release dates for Air-Cooled - 1925?
Air-Cooled - 1925 was released on: USA: 18 October 1925
Is oxygen a liquid or solid?
Oxygen is usally a Gas. It can be liquified if cooled past its boiling point. And it can become a solid if cooled past its melting point. Oxygen can be in all three states but is usally in the state of Gas.
Is melting candle wax a solid?
it's both solid and liquid. When it's cooled it's a solid, then when it is heated it's a liquid.
What is the silicate mineral with the lowest melting temperature?
All the silicates are molten at about 1200°C and all are solid when cooled to about 600°C.
Is melting iron is a or physical change?
Melting of any element, including iron, is a physical change. Melting is just a transition between states of matter, from solid to liquid. The solid state of iron can be regained if the liquid iron is cooled; so this denotes a physical change. There is no change to the chemical composition of iron during melting.
Can Mercury be changed from a liquid to a solid?
Yes, its melting point is -40 degrees C. If you cooled it below this it would freeze .... becoming a solid
The major result of heavy rains or melting snow and ice is?
because salt melts down ice and keeps the coldness away from being cooled
What volcanic rock is cooled lava made up of?
Igneous rock is made up of volcanic rock that is cooled after flowing as lava. Much of this type of rock is made up of sulphur and iron. Crystals also form from this type of melting.
