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?

Respuesta :

Answer:

Since the temperature is -6 C after 3 hours when rounded to the nearest whole degree we have to do the following

Step-by-step explanation:

Temperatures= -14.96 and 2.9

Subtract to get the value=

Estimate the value to:

3+1=4

Thus, your answer is -7 C
