Hey, I'm having problems with this question:(adsbygoogle = window.adsbygoogle || []).push({});

According to Newton's law of cooling, what cools faster, a person from 150 degress celcius to 100 degrees celcius or 100 degrees celcius to 50 degrees celcius in a laboratory environment? Why?

I' not really sure where to start.

I know the formula for this law is (T-Tr)= (To-Tr)e^-t/time constant

I guess wha I'm confused about is that I don't have some of the variables that I need like the time constant.

If anyone can point me in the right direction it would be much appreicated!

Thanks
