No, the formation of dew is condensation, which is a physical change.

∙ 13y agoExothermic. The grass is a cold place on the ground so the warm dew gives off heat to the grass. The way I think of it is exo means exit, so the warm water would be giving off heat or exiting.

∙ 12y agoit is neither, the dew on plants is the moisture in the air, attracted to the water inside the plant. Water has two partial charges (+ and -) that's why water has a high surface tention and is attracted to itself. Also dew on plants is the same as condensation on a glass of water

∙ 13y agoIt's endothermic because the fire needs to absorb energy to burn energy, which burn the fire and lets off heat.
Wiki User
∙ 10y agoNo, because it's not a "reaction" at all, it's a purely physical change of state. (An exothermic one, though, if you still care.)
Wiki User
∙ 9y agoBecause the water vapor in the air cools enough for the vapor to condense into water. It isn't made up of a new thing.

No as the dew again evaporates when it gets the Sun's heat.
I think it would surely help you friends .

Is formation of dew and rain a physical change?
Formation of dew and rain is not a chemical change, but a physical change. Often a change involving state of matter like in this case condensation (or like evaporation, melting, freezing, sublimation, or deposition) shows a physical change and not a chemical change.
Frost forming an grass in the morning chemical or physical?
Hence,the formation of dew and frost is a physical change.
Is dew on a windshield that changes to frost a physical property?
It is a physical change.
Is formation of water from its element physical change?
yes
What is type of change that doesnt involve the formation of a new kind of matter?
physical change

Hence,the formation of dew and frost is a physical change.
Is dew forming on a leaf a physical or chemical change?
It is a physical change because is it changing the leaf? No, no it isn't so it is a physical change.
Is a dew appearing on glass in the morning a physical change or a chemical change?
Physical change
Is dew on a windshield that changes to frost a physical property?
It is a physical change.
Is the buildup of a dew a physical change or chemical change?
Dew results from a physical change; water vapor condenses to become liquid water. Since it is still water, it has not experienced a chemical change.
Why is the formation of dew a physical change?
because the water molecules form together to form a liquid. molecules of water in the air (Vapour), form on a surface to form a liquid.
Is formation of water is a physical or chemical change?
physical change
Is the formation of stalagmites a physical or chemical change?
It is a physical change.
When dew on a windshield changes to frost is that a chemical change?
it is a physical change
Is oxide formation a physical change?
No. It is a chemical change.
Is formation of stalagmites in a cave a physical or chemical change?
it is physical
