Answer:
10.5kJ
Step-by-step explanation:
q=m⋅c⋅ΔT, where
q - heat absorbed
m - the mass of the sample
c - the specific heat of the substance
T - the change in temperature, defined as final temperature minus initial temperature
q = 100g x 4.18 J/G x C x (50.0 -25.0) C
cross out C and G
q = 10,450j
10,450J⋅1 kJ/10^3J=
10.5 kJ
or kilojoules
