The specific heat of a certain type of metal is 0.128 J/(g⋅∘C). What was the intial temperature if 0.305 kJ of heat is added to 82.6 g of metal to reach a temperature of 85.0 ∘C?

Question

56.15239104 is incorrect.

Answer 1

Q = mc(T_f-T_i)

I prefer to solve for the variable and sub in the given values with the appropriate units to check that the units mesh, to check my algebra, to make sure I am subbing in the correct quantities...

T_i = T_f - Q/mc (The only concern when plugging in is to write Q as 305 J
