The aim of investigating Boyle's Law in a Grade 11 practical worksheet for Term 3 is as follows:
Aim of the Investigation:
To verify Boyle's Law by demonstrating the relationship between the pressure exerted by a gas and its volume at constant temperature. Specifically, the objective is to show that the product of the pressure and volume of a fixed amount of gas remains constant when the temperature is held constant.
Background Information
Boyle's Law states that for a given mass of gas at constant temperature, the volume (V) of the gas is inversely proportional to the pressure (P) applied to it. Mathematically, this can be expressed as:
\[ P \propto \frac{1}{V} \] or \[ P \times V = k \]
Where \( k \) is a constant for a given amount of gas at a constant temperature.
Expected Outcomes
- To obtain data that demonstrates the inverse relationship between pressure and volume.
- To calculate the product of pressure and volume for different measurements to show that it remains constant.
- To develop a greater understanding of gas laws and the behavior of gases under pressure.
Practical Procedure
- Set up the apparatus with a gas syringe and a pressure sensor.
- Keep the temperature constant and gradually change the volume of gas.
- Record the corresponding pressure readings at various intervals of volume.
- Plot the data on a graph to visualize the inverse relationship.
- Analyze the data to verify Boyle's Law.
This investigation allows students to engage with experimental physics and apply theoretical concepts in a practical context, enhancing their understanding of gas behavior.
