Sulphuric acid is a dehydrating agent.

Dehydrating agents are substances that are capable of absorbing the moisture in a particular substance.

Due to the strong affinity of sulphuric acid towards the water, sulphuric acid absorbs moisture present in the air and gets diluted. Hence the humidity in the surroundings decreases.
