Questions involving pressure are physics questions that test your understanding of the concept of pressure, how it is calculated, and how it applies in solids, liquids, and gases.
They may involve:
- Calculating pressure using formulas
- Explaining real-life applications
- Understanding liquid pressure
- Understanding atmospheric pressure
- Applying Blaise Pascal’s Principle
- The figure below shows Hare’s apparatus used for comparing liquid densities.
Use the information given in the above diagram to calculate the density of liquid x given that density of water is 1000kgm-3 (2mks)
answer
$$
\delta_w g h_w = \delta_wgh_x $$
$$delta_x = \frac{1000 \times 30}{25} = 1200kgm^{-3}$$
$$1000 \times 30 = \delta_x \times 25 \
$$
