Answer 1

what are the formulas that are involved here?

Answer 2

use this
\[final temperature T _{f} =\frac{ m _{1} T _{1} + m _{2} T _{2} }{ m _{1} + m _{2} }\]

m1: mass 1 ,T1: temperature 1
m 2: mass 2 ,T 2: temperature 2

Answer 3

Keep in mind that only works whenever the specific heat of each object in question is =.
