In a practical worksheet for Grade 11 students to verify Boyle's Law, the independent variable is usually the pressure applied to a gas. Boyle's Law states that for a given mass of gas at constant temperature, the volume of the gas is inversely proportional to the pressure applied to it.
Here’s how you can structure it:
- Independent Variable: Pressure (P)
- Dependent Variable: Volume (V) of the gas
- Control Variables: Temperature of the gas, amount of gas, type of gas, and any equipment used (like the syringe or pressure gauge).
In the experiment, students can change the pressure applied to a sample of gas within a closed system (for example, by compressing it in a syringe) and measure the resulting volume to observe the relationship between pressure and volume.
