Answer:
27.25°C
Explanation:
hello,
this question involves heat transfer in an object and to find the final temperature, we'll use formula for heat transfer
data;
mass = 12g
heat energy (Q) = 12J
initial temperature (T1) = 25°C
final temperature (T2) = x
specific heat capacity (c) = 0.444J/g°C
heat energy(Q) = mcΔt
Q = mc(T2 - T1)
the final temperature was 27.25°C
