It is highly volatile.

It has high specific latent heat of vaporisation.

It is easily liquified on applying pressure even at room temperature.

(ii) Ammonia solution emulsifies fats, greases, etc. As a result, it can be used as cleaning agent for clothes, utensils, flooring, glass, porcelain, etc.
