We have that the energy required to raise the temperature of the radiator-water system by
1°K
E=116.85KJ
From the question we are told
A radiator made out of iron of specific heat capacity 450 J/kgk has a mass of 45.0 kg and is filled with 23.0 kg of water of specific heat capacity 4200 J/kgK.
Determine the energy required to raise the temperature of the radiator-water system by 1°K
Generally the equation for the Energy is mathematically given as
[tex]E=((mc)_i+mc_w)dt\\\\Therefore\\\\E=(45* 450 +4200*23)1\\\\E=116850J\\\\E=116.85KJ\\\\[/tex]
Therefore
the energy required to raise the temperature of the radiator-water system by
1°K
E=116.85KJ
