Answers to AQA GCSE Explaining pressure in a column of liquid
Practice Questions
1. State how the pressure of a liquid changes with depth of the liquid
As the depth of liquid increases, pressure increases
2.Explain why the pressure of a liquid will change with depth of liquid
At greater depth of liquid (or height from surface) there is more weight of liquid above, so the pressure increases.
3.Use the table below to answer the following questions
| Liquid | Density (kg/m3) |
|---|---|
| Water | 1000 |
| Oil | 920 |
| Mercury | 13560 |
| Ethanol | 789 |
Select the correct option below which ranks the liquids in order of increasing pressure exerted on a submerged object
a)Oil-Ethanol-Water-Mercury
b)Ethanol-Oil-Water-Mercury
c)Mercury-Water-Oil-Ethanol
d)Water-Mercury-Oil-Ethanol
