*will mark brainliest! answer * at the beginning of a 10-hour experiement a substance has an initial temperature of 19.7 degrees c. the substance is cooled at a constant rate of 2.6 degrees c per hour. what is the temperature of the substance at the end of the experiment?

At the end of the experiment, the temperature is at -6.3 degrees Celsius.

Step-by-step explanation:

We know that each hour, the temperature is going down by 2.6 degrees. Since we know this experiment went on for 10 hours, we'd multiply 2.6 by 10 to see how much the temperature went down over the course of the experiment. We get the answer that it went down by 26 degrees.

Since it was at 19.7 degrees in the beginning of the experiment and then went down by 26 degrees, we'd subtract 26 from 19.7. This gets us to our final answer, -6.3 degrees Celsius.
