Exothermic. The wet, warm air finds a cold surface, grass or the ground, it gives up heat energy, the vapour turns to liquid.
Exothermic. 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.
it 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
It's endothermic because the fire needs to absorb energy to burn energy, which burn the fire and lets off heat.
No, because it's not a "reaction" at all, it's a purely physical change of state. (An exothermic one, though, if you still care.)
Because the water vapor in the air cools enough for the vapor to condense into water. It isn't made up of a new thing.

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?
Yes, the change of dew to frost on a windshield is a physical property. This change involves a physical process (condensation turning to solid ice) without altering the chemical composition of the substance.
What is type of change that doesnt involve the formation of a new kind of matter?
physical change
Is syrup coming out of a tree a chemical or physical change?
The flow of this liquid is a physical phenomenon; but the formation of this "syrup" is a chemical change.
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 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 dew forming on grass in the morning a chemical change?
No, dew forming on grass in the morning is not a chemical change. Dew formation is a physical change, as it involves the water vapor in the air condensing into liquid water on the surface of the grass due to a decrease in temperature. This process does not involve any chemical reactions or the formation of new substances.
Is a dew appearing on glass in the morning a physical change or a chemical change?
Physical change
Why is the formation of dew a physical change?
The formation of dew is a physical change because it involves a phase transition from water vapor (gas) to liquid water (liquid) due to the cooling of air at night. No new substances are formed during this process, and the water molecules remain the same chemically before and after the dew forms.
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.
Is dew on a windshield that changes to frost a physical property?
Yes, the change of dew to frost on a windshield is a physical property. This change involves a physical process (condensation turning to solid ice) without altering the chemical composition of the substance.
When dew on a windshield changes to frost is that a chemical change?
No, the change from dew to frost is a physical change, not a chemical change. It is a result of the water vapor in the air cooling and forming ice crystals on the surface of the windshield.
Is the formation of stalagmites a physical or chemical change?
It is a physical change.
Is formation of water is a physical or chemical change?
physical change
Is oxide formation a physical change?
No. It is a chemical change.
