Question

NEED IT QUICK! THANK YOU At the start of an experiment, the temperature of a solution was Negative 12 degrees Celsius. During the experiment, the temperature of the solution rose 5 degrees Celsius each hour for 4 hours. Then the temperature changed by Negative 3 degrees Celsius and remained steady. What was the final temperature of the solution?

Negative 11 degrees Celsius
5 degrees Celsius
Negative 5 degrees Celsius
11 degrees Celsius

Answer 1

5 degrees celsius

Explanation:

C

Answer 2

5 degrees Celsius

Explanation:

initial temperature = -12°C

temperature after 4 hours = -12°C + 4(5°C)

= -12°C + 20°C

= 8°C

final temperature = 8°C - 3°C

=5°C
