Here's why:

* Boiling point is the temperature at which a liquid changes into a gas (vapor).

* The statement "alcohol boils at 60 degrees" indicates the specific temperature at which a particular alcohol transitions from a liquid to a gaseous state.

It's important to note that:

* Different alcohols have different boiling points. For example, methanol boils at 64.7°C, while ethanol boils at 78.37°C. So, the statement "alcohol boils at 60 degrees" likely refers to a specific type of alcohol.

* Boiling point is a physical property. This means it can be observed and measured without changing the chemical composition of the substance.
