Question: Which of the following is an application of Boyle’s law?
- Inflating a bicycle tire
- Cooking food in a pressure cooker
- Measuring the volume of a gas in a closed container
- Heating a gas in an open container
Answer: B) Cooking food in a pressure cooker
Solution: Boyle’s law, a fundamental principle in the field of physics and chemistry, describes the relationship between the pressure and volume of a gas at constant temperature. It states that the pressure of a gas is inversely proportional to its volume when the temperature remains constant. This law has numerous applications in our daily lives.
One significant application of Boyle’s law is option B, cooking food in a pressure cooker. This increase in pressure and temperature allows food to cook faster.
- Option A, inflating a bicycle tire, is more related to Charles’s law, which describes the relationship between the volume and temperature of a gas.
- Option C, measuring the volume of a gas in a closed container, is not a direct application of Boyle’s law. It’s more closely related to the ideal gas law, which combines Boyle’s, Charles’s, and Avogadro’s laws.
- Option D, heating gas in an open container, does not adhere to Boyle’s law either. Boyle’s law specifically deals with a constant temperature, and heating gas in an open container would typically lead to an increase in both pressure and volume, not the inverse relationship described by Boyle’s law.
In summary, the correct application of Boyle’s law is cooking food in a pressure cooker, where the law’s principles of pressure and volume inversely affecting each other play a crucial role in the cooking process.
