No, evaporation is a physical process in which a liquid substance changes into a gas state at a temperature below its boiling point. Unlike chemical reactions, evaporation does not involve any change in the chemical composition or structure of the substance.

Is evaporation of dry ice a decomposition reaction?
No, the evaporation of dry ice is a physical change, not a decomposition reaction. Dry ice is solid carbon dioxide, and when it evaporates, it changes directly from a solid to a gas without undergoing a chemical reaction.
When liquid becomes a water vapor is that a chemical reaction?
No, the change from liquid water to water vapor is a physical change called evaporation. In a chemical reaction, the substances are transformed into different substances with new chemical properties.
How would you write the equation to show water evaporation?
The equation for water evaporation can be represented as: H2O (liquid) → H2O (gas) This shows the process where liquid water turns into water vapor through evaporation.
Which in the following events is not a common sign that a chemical change taken place?
For example melting, boiling, evaporation, transformation in powder are not signs of a chemical reaction.
What are the uses of round bottle flask?
Examples are: distillation, chemical reaction with reactants in solution at high temperature, evaporation.
Is gasoline being evaporated a chemical reaction?
No. Evaporation is a physical process.
Is evaporation of water from a lake a chemical reaction?
No, evaporation of water from a lake is a physical process, not a chemical reaction. It involves the transformation of water from a liquid to a gas without any change in the chemical composition of water molecules.
Is the drying of wet laundry a chemical reaction?
No, it is a physical process - water evaporation.
Is evaporation a chemical or physical reaction?
Evaporation represents the uptake of energy by the liquid that results in a physical change. (phase or state of matter)
Evaporation and condensation are what reaction?
Not chemical reactions, but change of phases
Is evaporation of dry ice a decomposition reaction?

No, the change from liquid water to water vapor is a physical change called evaporation. In a chemical reaction, the substances are transformed into different substances with new chemical properties.
Is vapour a chemical reaction?
Vapor is not a chemical reaction itself. It is the gaseous state of a substance that was previously in liquid or solid form. The process of creating vapor from a liquid or solid can involve a physical change (such as evaporation) rather than a chemical reaction.

The equation for water evaporation can be represented as: H2O (liquid) → H2O (gas) This shows the process where liquid water turns into water vapor through evaporation.

Examples are: distillation, chemical reaction with reactants in solution at high temperature, evaporation.
What is the balance of chemical equation involve in evaporation?
Evaporation is not a chemical change and so there is no chemical equation.
