Question 4
Explain which container has the highest pressure at the bottom, and which container has the lowest. Use information from Figure 3 and Figure 4.
Worked Solution & Example Answer:Explain which container has the highest pressure at the bottom, and which container has the lowest - Edexcel - GCSE Physics - Question 4 - 2016 - Paper 1
Step 1
Identify the Key Factors Affecting Pressure
Answer
The pressure at the bottom of a container filled with fluid is influenced by two main factors: the height of the fluid column above the point of measurement and the density of the fluid. The pressure can be calculated using the formula:
ho g h$$ where $P$ is the pressure, $\rho$ is the density of the fluid, $g$ is the acceleration due to gravity, and $h$ is the height of the fluid column.Step 2
Step 3
Conclusion on Highest and Lowest Pressure
Answer
Based on the identified factors and analysis of the figures:
- The container with the highest fluid column will have the highest pressure at the bottom.
- Conversely, the container with the lowest fluid column will exhibit the lowest pressure at the bottom.
