Sublimation is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water. The opposite of sublimation is "deposition", where water vapor changes directly into ice-such a snowflakes and frost.

How do you use sublimation in sentence?

If the air is cold and dry ice can change directly into water vapour, by sublimation.


What is water vapor deposition?

Water vapour depostion is water vapour transforming directly to ice without condensing first.


Is ice cream melting a change of state?

Transformatiom from liquid water to solid water (ice).


What is the different between ice and water?

Ice is the solid form of water (H2O) and water vapour. water is the liquid form of water vapour and ice.


Why is condensation of water vapor is a chemical change?

It's not !... It's a physical change. Chemically - whether water is frozen into ice, is liquid as water or a vapour (steam) - it's still the same substance.


What is wave deposition?

Water vapour depostion is water vapour transforming directly to ice without condensing first.


Which processes of the water cycle show heat being added and which ones show heat beign removed?

How the water cycle and heat are related: Adding or subtracting heat makes the water cycle work. If heat is added to ice, it melts. If heat is added to water, it evaporates. Evaporation turns liquid water into a gas called water vapour. As water goes through its cycle, it can be a solid (ice), a liquid (water), or a gas (water vapour). Ice can change to become water or water vapour. Water can change to become ice or water vapour. Water vapour can change to become ice or water. If heat is taken away from water vapour, it condenses. Condensation turns water vapour into a liquid. If heat is taken away from liquid water, it freezes to become ice. The water cycle involves the sun heating the Earth's surface water and resulting in the surface water evaporating. The water vapour rises into the Earth's atmosphere. The water cools and condenses into liquid droplets. The droplets grow until they are heavy and fall to the earth as precipitation (which can be rain, freezing rain or snow).


Explain why water freezing is not a chemical change.?

Because the chemical formula remain the same - liquid water or ice or vapour.


How will you justify that ice and water and water vapour are the states of a substance and not substance?

we know that the water is H2O and the ice is H20 and the water vapour is H20. so we can tell that these are all the states of water.


What are all of the states of water?

Ice. Liquid. Vapour.


What is the equation for water vapour?

It is still H20 if it is ice, water, or steam.


What can be a liquid solid and gases?

Water - water, ice and steam/vapour
