Question

In a lab, a substance was cooled by 28c over a period of 7 hours at a constant rate. What was the change in temperature each hour?

Answer 1

Answer:

4 degrees celsius per hour

Step-by-step explanation:

As we know the rate of change is constant then we can find the

rate of change by simply dividing the total change in temperature by the

time elapsed. Hence, $\frac{\Delta T}{\Delta t} = \frac{28}{7} = 4$ celsius per hour.
