Activity 7: (Page-117)
What is the effect on pressure of the liquid, when height of the water column is increased?
Ans:
With the increase in height of the water column, pressure also gets increased.

Answer 1

liquid coloumn is inversely proportional to density

Answer 2

Pressure Directly Proportional to Height

Explanation:

• Water pressure is the consequence of the heaviness of all the water above pushing down on the water beneath.

• As we go further into a waterway, there is more water above, and hence a more prominent weight pushing down.

• This is the why water pressure increments with profundity.
• We know that, P = $\rho\times g\times h$ which convey that pressure is directly proportional to height. Hence, the more deeper an object goes, the more is the pressure felt.
