The more the area of contact of a given body the ______________ the pressure it will exert.

A ___________________ is a simple device used to measure liquid pressure.

The pressure exerted by water in the oceans _________________ with depth.

A manometer has a ______________ glass tube which is fixed to a wooden board having a scale.

Objects in a liquid are buoyed _____________________ because the pressure acting up against the bottom of the object exceeds the pressure acting down against the top.

If an enormous amount of pressure is acting on us, we do not feel it, this is because the pressure of the blood in our blood vessels and that of the other fluids present in the body _______________the atmospheric pressure.

(b) Pressure is a scalar quantity.

Which of the following are correct :

(a) Atmospheric pressure is defined as the pressure exerted on an object by the weight of the air above it.

(b) The atmospheric pressure on the Earth's surface at sea level is about one hundred thousand pascal, i.e., 100 kPa.

Which of the following are correct :

(a) The tractors have tyres, to creates more pressure on the ground, so that tyres sink into comparatively soft ground in the field.

(b) The handles of bags, suitcases, etc. are made broad, so that more pressure is exerted on the hand.

(c) Buildings are provided with broad foundations, so that the pressure exerted on the ground becomes more.
