Question

At the lab experiment the temperature of a liquid was 15 C. The temperature of the liquid was lowered by 9.5 C every hour for 3 1/2, and then the final temperature was recorded. What was the final temperature of the liquid?

Answer 1

If the temperature was lowered by 9.5 C every hour for 3 1/2 hours, the total temperature decrease is:

9.5 x 3.5 = 33.25 C

So, the final temperature is:

15 - 33.25 = -18.25 C

This means the liquid's final temperature is -18.25 degrees Celsius.
