Complete question :
A chemist is raising the temperature of a liquid. The temperature is now --8.4 degrees Celsius and is increasing by 1.6 degrees Celsius per minute. How many minutes will it take it for it to take to get to 0 degrees Celsius
Answer:
5.25 minutes
Explanation:
Given that :
Current temperature = - 8.4°C
Rate of change = 1.6°C per minute
For the temperature to be 0°C ; it will take
(Final temperature - current temperature) rate of change
(0°C - (-8.4°C)) / 1.6°C
(0°C + 8.4°C) / 1.6°C
8.4°C / 1.6°C
= 5.25 minutes
