Answer:
S = 27500J / 308.15molK
Explanation:
Entropy measures the degree of disorganization of a system. It is measured in the entropy change that is equal to the heat exchanged divided by the temperature at which the process occurs.
S2-S1 = Q / T
S = entropy
Q = heat = 27.5 kJ / mol * 1000J / 1KJ = 27500J / mol
T = temperature = 35 + 273.15 = 308.15K
units = J / molK
S = 27500J / 308.15molK
The correct answer is
C. The battery
The battery is a device that provides a potential difference in the circuit, and so an electromotive force (e.m.f.) which pushes the electrons in the circuit from the negative pole towards the positive pole of the battery, so they move through the circuit. Therefore, it provides electrical energy.
increased with an increased current flow
