Yes, alcohol readily changes to a gas (vapour) at room temperature.
They change from a liquid to a vapor (gas).
Alcohol vaporizing is a physical change because it does not involve a change in the chemical composition of the alcohol molecules. It is simply a phase change from liquid to gas.
No. It is a physical change as the actual compound does not change, only its state does.
Physical; from liquid to gas, but it's still alcohol.
Evaporation of ethyl alcohol is a physical change. This is because evaporation involves only a change in the physical state of the substance from liquid to gas, without altering its chemical composition.

No. It is a physical change as the actual compound does not change, only its state does.
No. The chemical structure of ethyl alcohol gas is the same as ethyl alcohol liquid.
Physical; from liquid to gas, but it's still alcohol.
Alcohol at 78 ° C is converted to gas. Water at 100 ° C is converted to gas.
Evaporation of ethyl alcohol is a physical change. This is because evaporation involves only a change in the physical state of the substance from liquid to gas, without altering its chemical composition.
Evaporation of ethyl alcohol in a watch glass is a physical change, not a chemical change, because it does not alter the chemical composition of the alcohol. The process only involves a change in state from liquid to gas.
Happy little gases! When alcohol and mercury are heated, they transform from a liquid state to a gaseous state. Just like when we paint, sometimes things change form to create something new and beautiful.
The boiling point of pure ethanol is 78,37 0C.
Is a physical change as the alcohol is changing states
Evaporation is a physical process - transformation of a liquid in gas without boiling.
