Answer:
voltage source
Explanation:
establishes an electric potential difference across the two ends of the external circuit and thus causes the charge to flow. The voltage source is the numerical value of this electric potential difference.
Answer : The specific heat (J/g-K) of this substance is, 0.780 J/g.K
Explanation :
Molar heat capacity : It is defined as the amount of heat absorbed by one mole of a substance to raise its temperature by one degree Celsius.
1 mole of substance releases heat = 92.1 J/K
As we are given, molar mass of unknown substance is, 118 g/mol that means, the mass of 1 mole of substance is, 118 g.
As, 118 g of substance releases heat = 92.1 J/K
So, 1 g of substance releases heat = ![\frac{92.1}{118}=0.780J/g.K](https://tex.z-dn.net/?f=%5Cfrac%7B92.1%7D%7B118%7D%3D0.780J%2Fg.K)
Thus, the specific heat (J/g-K) of this substance is, 0.780 J/g.K
