The internal energy of the ideal gas is zero
The change in internal energy for an isothermal process is zero.
An ideal gas has no interactions between particles, therefore no intermolecular forces.
pressure change at constant temperature does not change the internal energy.
Adiabatic throttling expansion has less work done and lower heat flow.
That lower the internal energy.
The temperature decreases during the adiabatic expansion
Hence the internal energy of the ideal gas is zero

A battery transforms two types of energy, chemical energy to electrical energy.
Answer: Chemical and electrical energy
The enthalpy of the reaction is obtained as 4.876 kJ.
<h3>What is the enthalpy?</h3>
The enthalpy of a reaction is the heat that is absorbed or emitted in a reaction.
Given the reaction; N2(g) + 3H2(g) ⇔2NH3(g);
Number of moles of N2 = 6.44 grams/28 g/mol
= 0.23 moles
If 1 mole of N2 releases 21.2 kJ of energy
0.23 moles of N2 releases 0.23 moles * 21.2 kJ /1 mole
= 4.876 kJ
