Question

Water freezes at 0°C. If we cool water initially to 97°C at a rate of 6°C per minute, will it be frozen in 16 minutes? Explain.

A) Yes, because 97 - 6 × 16 = 1.
B) No, because 97 - 6 × 16 = 1.
C) Yes, because 97 + 6 × 16 = 193.
D) No, because 97 + 6 × 16 = 193.

Answer 1

The water will not be frozen in 16 minutes, as the final temperature is calculated to be 1°C.

Step-by-step explanation:

Water freezes at 0°C. In this scenario, the water initially cools from 97°C to 0°C at a rate of 6°C per minute. To determine if the water will be frozen in 16 minutes, we can calculate the final temperature by subtracting the rate of cooling (6°C per minute) multiplied by the time (16 minutes) from the initial temperature (97°C). Using the formula 97 - 6 × 16, we find that the final temperature is 1°C.

Therefore, the correct answer is option B) No, because 97 - 6 × 16 = 1.
