State two percussions that must be followed in this investigation of grade 11 practical worksheet term 3 verify Boyle's law

Answer 1

When investigating Boyle's Law in a Grade 11 practical worksheet, the following two precautions should be followed:

1. Ensure Proper Sealing of Equipment: When working with the gas apparatus, ensure that all connections (such as the gas syringe and any tubing) are securely sealed to prevent gas leaks. A leak would lead to inaccurate pressure and volume measurements that could invalidate the results.

2. Calibrate Measurement Instruments: Before beginning the experiment, ensure that all measuring instruments (like pressure gauges and volume measuring devices) are properly calibrated. This ensures that the data collected is accurate and reliable, which is essential for verifying Boyle's Law correctly.

By following these precautions, students can minimize errors and obtain valid results in their investigation.
