Question

In Pascal's law fluid pressure depends-
1. On the shape of the pot
2. On melting point  
3. On boiling point  
4. on depth (presence of gravity)

Answer 1

Correct Answer - Option 1 : On the shape of the pot

The correct answer is option 1

Fluid pressure does not depend on the shape of the pot.

• If gravitational effect = 0, The pressure at each point inside the fluid is the same.
• If gravitational effect = Present, Fluid pressure increases with depth.
• Effect on melting point - Substances that increase volume due to the effect of heat, their melting point also increases when pressure is increased. Example – Wax
• Substances that reduce volume due to the effect of heat, their melting point also decreases when pressure is increased. Example – Ice
• Effect on boiling point - The boiling point of all the fluids increases by increasing the pressure.
