Respuesta :
The amount of heat generated is 654.5 joules.
q=mCΔT
Given,
m=100, C=0.385 j ⁄ g · °c, [tex]T_{1} =18^{0}C , T_{2} =35^{0} C[/tex],
q=100*0.385*(35-18)= 654.5 j
Heat
Heat is defined as energy that is transferred to or from a thermodynamic system by means other than thermodynamic work or the movement of matter (e.g. conduction, radiation, and friction). Similar to thermodynamic work, heat transfer affects a system's surrounds in addition to the system itself; as a result, it is not a characteristic of the system alone, even while it helps to change the internal energy of the system, which is a property of the system alone. This differs from the common linguistic usage of the word "heat" as a system feature in and of itself. The quantity of energy that is transported as heat in a process is the amount of energy that has been transferred minus any thermodynamic work that has been done and any energy that has been contained in the substance being moved.
