The rate of cooling of the water, whose temperature decreases from 60 °C to 35 °C in 10 minutes, is -2.5 ° C/min.
Initially, we have water at 60 °C. After 10 minutes, its temperature decreases to 35 °C. The rate of cooling of the water is equal to the change in its temperature over the elapsed time.
[tex]r = \frac{35 \° C - 60 \° C }{10 min} = -2.5 \° C/min[/tex]
The rate of cooling of the water, whose temperature decreases from 60 °C to 35 °C in 10 minutes, is -2.5 ° C/min. That is, its temperature decreases by 2.5 °C every minute.
