14. 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?
Answer: B
The boiling point of water at point B is 232°F.
At point B, the boiling point of water is 20°F higher than at point A, which boils at 212°F. Therefore, the boiling point at point B is calculated as 212°F + 20°F, resulting in 232°F.
A) 424°F
This option is incorrect because it suggests an increase in boiling point that is significantly higher than the 20°F increase specified in the question. The correct increase leads to a boiling point of 232°F, making 424°F an unrealistic option.
B) 232°F
This is the correct answer, as it accurately reflects the boiling point of water at point B after accounting for the 20°F increase over the 212°F boiling point at point A. This calculation aligns perfectly with the information given in the question.
C) 389°F
This option is incorrect because it implies a much larger increase than the 20°F mentioned. The increase calculated from point A's boiling point does not reach anywhere near 389°F, which is inconsistent with the data provided.
D) 100°F
This option is also incorrect as it suggests a boiling point significantly lower than that of point A. The boiling point of water cannot decrease to 100°F when it is 212°F at point A, making this choice invalid in the context of the question.
Conclusion
The correct boiling point at point B is definitively 232°F, which results from a straightforward addition of the 20°F increase to the boiling point at point A. Other options fail to reflect the precise increase specified in the question, thus illustrating a misunderstanding of the relationship between the two points.
