a scientist measures the change in the temperature of a chemical solution. at the start of the experiment, the solution is at a temperature of - 12.94°c. the temperature changes by - 1.9°c each hour. what is the temperature of the solution after 4 hours?
Answer
Explanation:
Step1: Find the total temperature change
The temperature changes by - 1.9°C each hour for 4 hours. So the total change in temperature is the product of the change per hour and the number of hours. $(-1.9)\times4=-7.6$
Step2: Calculate the final temperature
The initial temperature is - 12.94°C. Add the total change in temperature to the initial temperature. $-12.94+(-7.6)=-20.54$
Answer:
$-20.54$
