Evaporation is a physical change- it is still alcohol. The change can be undone by colling the air and condensing the ethyl alcohol vapor back to liquid alcohol.
The smell of alcohol is not a physical change; rather, it is the result of the volatile compounds in alcohol evaporating into the air. When alcohol evaporates, it changes from a liquid to a gas, which can be detected by our sense of smell. This process is a physical change, as it involves a change in state without altering the chemical composition of the alcohol itself.
The temperature at which dry ice evaporates is a physical property. It is the sublimation point of carbon dioxide, where it changes directly from a solid to a gas without passing through the liquid phase.
physical or chemical changes
Density is classified as a physical property because the density of a substance can change when the substance changes state. Example: When water evaporates it is a physical change and the density changes. A chemical property is a property that describes its ability to react chemically with other substances and THEREFORE density is not a chemical property.
Physical. If water evaporates, it is still water. It does not change into a different substance. A Chemical change is when something changes into a different substance. For example, when wood is burned, it changes into a different substance(ash).
When ethyl alcohol evaporates, it is a physical change because the chemical composition of the alcohol remains the same. Evaporation is a process in which a substance changes from a liquid state to a gaseous state without undergoing a chemical reaction.
No. It is a physical change as the actual compound does not change, only its state does.

Rust forming on a nail is a chemical change. All the others are physical changes.

Changes in matter are either physical or chemical. Matter changes physically when it liquefies, evaporates, freezes, etc., and chemically when it combines with other types of matter in chemical compounds.
Brewing beer involves both physical and chemical changes. Physical changes include crushing grains and boiling water, while chemical changes occur during fermentation when yeast converts sugars to alcohol and carbon dioxide.
The temperature at which dry ice evaporates is a physical property. It is the sublimation point of carbon dioxide, where it changes directly from a solid to a gas without passing through the liquid phase.
No because physical states of matter changes are physical changes. they are not chemical changing meaning it is still alcohol, just frozen.
Boiling of ethyl alcohol at 79 degrees Celsius is a physical change. It is a reversible process where the alcohol changes from liquid to vapor state without undergoing a chemical reaction.
There are no physical changes. there are only chemical changes.
It is a physical change. The molecules of the alcohol are still there, there are just spread out.
