Question

A scientist changes the temperature of a solution at a rate of -8°C per minute. How many minutes will it take for the solution's temperature to change from 0°C to -88°C?

A) 80 min
B) 11 min
C) 96 min
D) 704 min

Answer 1

The solution's temperature will change from 0°C to -88°C in 11 minutes.

Step-by-step explanation:

To find the number of minutes it will take for the solution's temperature to change from 0°C to -88°C, we can use the formula:

Time = (Final Temperature - Initial Temperature) / Rate of Temperature Change

In this case, the final temperature is -88°C, the initial temperature is 0°C, and the rate of temperature change is -8°C per minute. Plugging these values into the formula, we get:

Time = (-88 - 0) / -8 = 88 / 8 = 11 minutes

Therefore, it will take 11 minutes for the solution's temperature to change from 0°C to -88°C.
