At the start of an experiment, the temperature of a solution was -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 -3 degrees Celsius and remained steady. What was the final temperature of the solution?

A. -11 degrees Celsius
B. 5 degrees Celsius
C. -5 degrees Celsius
D. 11 degrees Celsius

Answer :

Answer:

5 degrees Celsius

Step-by-step 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

Answer:

5 degrees celsius

Step-by-step explanation:

C
