Answer: Batteries have three parts
Explanation:
Batteries have three parts, an anode , a cathode , and the electrolyte. The cathode and anode the positive and negative sides at either end of a traditional battery are hooked up to an electrical circuit. The chemical reactions in the battery causes a build up of electrons at the anode.
Answer:
= 1.47kJ/K
Explanation: <u>Entropy</u> is the measure of a system's molecular disorder, i.e, the unuseful work a system does.
The nitrogen gas in the insulated tank can be described as an ideal gas, so it can be used the related formulas.
For the entropy, the ratio of initial and final temperatures is needed and as volume is constant, we use:




<u>Specific</u> <u>Heat</u> is the quantity of heat required to increase the temperature 1 degree of a unit mass of a substance. Specific heat of nitrogen at constant volume is
0.743kJ/kg.K
The change in entropy is calculated by
![\Delta S= m[c_{v}ln(\frac{T_{2}}{T_{1}})-Rln(\frac{V_{2}}{V_{1}} )]](https://tex.z-dn.net/?f=%5CDelta%20S%3D%20m%5Bc_%7Bv%7Dln%28%5Cfrac%7BT_%7B2%7D%7D%7BT_%7B1%7D%7D%29-Rln%28%5Cfrac%7BV_%7B2%7D%7D%7BV_%7B1%7D%7D%20%29%5D)
For the nitrogen insulated in a rigid tank:
![\Delta S= m[c_{v}ln(\frac{T_{2}}{T_{1}})]](https://tex.z-dn.net/?f=%5CDelta%20S%3D%20m%5Bc_%7Bv%7Dln%28%5Cfrac%7BT_%7B2%7D%7D%7BT_%7B1%7D%7D%29%5D)
Substituing:
![\Delta S= 3[0.743ln(1.94)]](https://tex.z-dn.net/?f=%5CDelta%20S%3D%203%5B0.743ln%281.94%29%5D)

The entropy change of nitrogen in an insulated rigid tank is 1.47kJ/K
