Question

Identify the correct option based on the following statements

i) water exerts pressure on the bottom of the bottom of the tank.

ii) water exerts pressure on the wall of the tank

a) Only (i)
b) Only (ii)
c) Both (i) and (ii)
d) Neither (i) and (ii)​

Answer 1

Answer:

Only (ii)

Explanation:

Pressure is actually defined as force per unit area.

So, we need to keep in mind that actually partiality won't exist in case of general units (here;pressure) so, the pressure exerted in the walls of container are exerted on all the sides and not specifically to one side.

An experiment to find out can be :

1. Take small pieces if paper (better if torn)

2. Take a container, put it in a tripod stand.

3. Now, take some water and pour it into the container, start heating it.

4. Put the paper pieces in the water.

Observation: You will see that the paper pieces go to the borders of the container (cold side)

Actually this activity is somewhat related to heat, but I tried to show the presence of pressure here.
