9.1

Postby Jason Liu 1C » Sun Jan 28, 2018 10:40 pm

For homework problem 9.1, the solutions manual says to use the temperature in Kelvin instead of Celsius, but it was given in Celsius in the problem. How do I know when to use Kelvin and when to use Celsius?

You should decide which one to use based on the units of the constant.

Usually there if there is a change in temperature involved in an equation, either unit is acceptable because it's only the change that is important.

The standard unit of temperature is Kelvin, so anytime the temperature is constant, use Kelvin. For changes in temperature, the change you get using Celsius and Kelvin are the same so you can just use Celsius. If you're not sure, just use Kelvin.
