A chemist is studying the boiling point of water at points A and B. At point A, the water boils at 212°F, while at point B, the boiling point increased by 20°F. What is the boiling point of the water at point B?

Rationale

The boiling point of the water at point B is 232°F.

At point A, the water boils at 212°F. The problem states that the boiling point increases by 20°F at point B, therefore the boiling point at point B is calculated by adding 20°F to 212°F, resulting in 232°F.

A (424°F) YOUR ANSWER

This choice incorrectly doubles the increase in boiling point, suggesting a miscalculation. The boiling point at point B is simply the original boiling point of 212°F increased by 20°F, not a further doubling of the result.

B (232°F) CORRECT

This is the correct answer, as it accurately reflects the increase of 20°F added to the initial boiling point of 212°F at point A.

C (389°F) YOUR ANSWER

This choice represents a substantial increase beyond the 20°F adjustment stated in the question. It does not relate to the initial boiling point of 212°F and therefore is an incorrect interpretation of the data provided.

D (100°F) YOUR ANSWER

This option suggests a significant decrease in the boiling point, which contradicts the information given. The boiling point cannot drop to 100°F given that the starting point is 212°F and the problem specifies an increase.

Conclusion

The correct boiling point of water at point B is 232°F, derived from the initial boiling point of 212°F with an increase of 20°F. Each incorrect choice either misinterprets the increase or fails to relate accurately to the original boiling point. Understanding how to apply the increase correctly is crucial for resolving problems involving boiling points in varying conditions.
