Answer 2

Required Answer :

(1) Volume :

• Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains.

• Volume is often quantified numerically using the SI derived unit, the cubic metre.

(2) Pressure :

• Pressure is defined as the physical force exerted on an object.

• The force applied is perpendicular to the surface of objects per unit area.

• The basic formula for pressure is F/A (Force per unit area).

• Unit of pressure is Pascals (Pa). Types of Pressures are Absolute, Atmospheric, Differential, and Gauge Pressure.
