The element that is a liquid at 60 degrees Celsius is bromine (Br).

Here's why:

* Bromine's melting point is -7.2 degrees Celsius. This means it's a liquid at temperatures above this point.

* Bromine's boiling point is 58.8 degrees Celsius. This means it transitions to a gas at temperatures above this point.

Therefore, at 60 degrees Celsius, bromine is a liquid.
