Explanation:
The given data is as follows.
Thickness (dx) = 0.87 m, thermal conductivity (k) = 13 W/m-K
Surface area (A) = 5
, 
According to Fourier's law,
Q = 
Hence, putting the given values into the above formula as follows.
Q = 
= 
= 5902.298 W
Therefore, we can conclude that the rate of heat transfer is 5902.298 W.
Answer:one gram by 1oC
Explanation: you will need to know the value of water's specific heat
The reaction given above is a combustion reaction. All combustion reactions are exothermic, meaning they give off heat when they react,
