Brownie · Answer 1

recall that heat absorbed released is given by

Q = mc * (T2 - T1)

where

m = mass (in g)

c = specific heat capacity (in J/g-k)

T = temperature (in C or K)

*note: Q is (+) when heat is absorbed and (-) when heat is released.

substituting,

Q = (480) * (0.97) * (234 - 22)

Q = 98707 J = 98.7 kJ
