What can be said about the hotness of water in buckets A and B?

• A. The water in bucket A is hotter than in bucket B.
• B. The water in bucket B is hotter than in bucket A.
• C. The water in buckets A and B is equally hot.
• D. Cannot be predicted

Answer 1

The correct option is B The water in bucket B is hotter than in bucket A.

• Himanshu feels hotness in his right hand after dipping it in normal water. So, the normal water is at a higher temperature than the water in bucket A.
• Similarly, he feels coldness in his left hand because the water in bucket B is warmer than the normal water.
• So, the order of temperature is as follows:

Bucket A < Bucket with normal water < Bucket B

• Therefore, the water in bucket B is hotter than that in bucket A.
