### 8.25

In this problem the temperatures are given in celsius but in the solution we use them in units of kelvin without adding 273. Why is this possible?

I'm pretty sure it is because the problem says "temperature rise of 7.32 C" rather than giving a specific temperature in celsius. This temperature rise would have been the same whether the degrees were celsius or kelvin, so either units can be used in the problem.

Yes! They were giving us the change in temperature. The change in temperature will be the same in Celsius or K.
