Understanding the Assertion and Reason
The question assesses the relationship between the assertion and reason regarding cooking in a pressure cooker.
Assertion (A): In a pressure cooker, food is cooked above boiling point.
- This statement is true.
- A pressure cooker operates by sealing steam inside, which raises the internal pressure.
- As a result, the boiling point of water increases, allowing food to cook at temperatures higher than the standard boiling point of 100°C (212°F).
Reason (R): Boiling point of water increases as the pressure increases.
- This statement is also true.
- The boiling point of any liquid, including water, is directly related to the surrounding pressure.
- When pressure increases, molecules require more energy (higher temperature) to escape into the vapor phase, thus raising the boiling point.
Relationship Between A and R
- While both A and R are true, R explains why A is true.
- The increased pressure in the cooker directly leads to an increased boiling point, enabling cooking at higher temperatures.
Conclusion
- Therefore, the correct answer is option A: Both A and R are true, and R is the correct explanation of A.
- This relationship highlights the fundamental principles of pressure and temperature in cooking processes.
By understanding these concepts, one can appreciate the efficiency of pressure cookers in preparing food quickly.
