Question

A weather balloon is at an altitude where the temperature is 3º C. The balloon ascends 900 ft with a decrease in temperature of 5º C. The balloon then ascends again with a decrease in temperature of 3º C. What is the final temperature?

Answer 1

Answer is -5°C.

Explanation:

Initial temperature = 3°C

First decrease in temperature = 5°C

Second decrease in temperature = 3°C

Balloon ascend = 900 ft

Total change in temperature = 3-5-3 = -5

Thus final temperature = -5°C
