Solve the problem.
-At the start of a chemistry experiment, Sarah measured the temperature of a liquid to be -16°C. At the end of the experiment, it had risen 29°C. What was the liquid's temperature at the end of the experiment?
A) -13°C
B) -45°C
C) 13°C
D) 45°C

Question

Quizplus · Accepted Answer

To find the final temperature, we need to add the change in temperature (29°C) to the initial temperature (-16°C). 
-16°C + 29°C = 13°C 
Therefore, the liquid's temperature at the end of the experiment was 13°C. To find the final temperature of the liquid, we need to add the temperature rise (29°C) to the initial temperature (-16°C):
-16°C + 29°C = 13°C
Therefore, the liquid's temperature at the end of the experiment was 13°C.
