Mercury is liquid at room temperature.

Mercury and water (yeah, I know it is a bad example) are liquid at room temperature.

Mercury and water (yeah, I know it is a bad example) are liquids at room temperature.

We need exercise.

We need exercises.

He is a man of amibition.

He is a man of ambitions.

How do you when you can use the generalised form?

These are the ones we use (though the other 2 are grammatically fine):

We need exercise.

He is a man of amibition.

I'm afraid I must guess that it is a matter of usage, collocation and set phrase. For instance, 'a man of + ambition/honor/strength/means' is a semi-fixed phrase.
