1.	4. Give definition of pressure. If there is increase orin area of a given force, explain what change would occurin pressure and give proper illustrations.
Answer» 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. While sipping beverages from a straw, have you noticed that you actually suck the air out of the straw? While you sip the beverage, you’re actually applying ‘Pressure’. By its very definition: Pressure = Force/Area. So for a given force if you decrease the area by a factor of two, then the pressure would increase by a factor of two.
