Explanation:
Pressure is the amount of force acting on a unit area of a surface.
Mathematically, pressure is given by
Pressure = Force / Unit Area
That is, pressure and area on which the force is applied has an inverse dependance.
Keeping force constant, if the area on which the force applied is increased, the pressure decreases.
In detail
Pressure is related with area on which it is applied. When the area is increased the pressure exerted is less. But when the area on which pressure is exerted is decrease the pressure increases. So we can conclude that pressure increases with decrease in area.

Whenever the pressure is applied on a liquid then it get condensed and form solid. Changes in pressure have a very little effect on the volume of Liquid.
