Question

Thermal physics! how do you rearrange the formula (q=mc ΔT) to the temp when you have everything except for the second temp, for the ΔT.

Answer 1

\[q=mc(T_f-T_i)\]
\[\frac{q}{mc}=T_f-T_i\]

@Katelyn96 , which temperature do you have the final or the initial

Answer 2

I only have the initial I think, its 20 degrees

Answer 3

\[\frac{q}{mc}+T_i=T_f\]

Answer 4

\[q=mcT_f-mcT_i\]
\[q+mcT_i=mcT_f\]
\[\frac{q}{mc}+T_i=T_f\]

Answer 5

that is another way

Answer 6

Okay, and this will work out the final temperature? :)

Answer 7

yes

Answer 8

okay, thank you so much for your help.
