The sulfuric acid can be constituted into different concentrations using distilled water as a diluent.
<h3>What is dilution of acid?</h3>
Dilution of acid is defined as the decrease in the concentration of an acid using water.
For sulfuric acid to be diluted, it is slowly added to distilled water using the following guidelines:
- Add 150 ml of water to the beaker and add the desired amount of acid. This will give a diluted concentration of the given acid.

Answer:
Vapour pressure of a liquid varies with temperature
Explanation:
The vapour pressure of any liquid is directly proportional to the temperature of the liquid. This implies that, as the temperature of the liquid increases, the vapour pressure increases likewise and vice versa.
Since the vapour pressure of liquid varies with the temperature of the liquid, it is essential to know the water temperature in the experiment to determine the vapour pressure of water.
