Question

The temperature of a solution in a science experiment is -6.2°C. Jesse wants to raise the temperature so that it is positive. (a) Give an example of a number of degrees Celsius by which Jesse could raise the temperature. (b) Write a equation to represent the solution.

Answer 1

Hello!

First, the temperature is -6.2ºC, and Jesse wants to raise it until be positive.

(a) Give an example of a number of degrees Celsius by which Jesse could raise the temperature.

If we add 6.2ºC, we will obtain a temperature equal to 0ºC, right? So, to the temperature be positive you can choose any temperature greater than 6.2º.

For example, I'll choose 15ºC.

(b) Write an equation to represent the solution. ​

We will write the current temperature plus the temperature that we will add, then we obtain the new temperature, look:

-6.2ºC + 15ºC = 8.8ºC
