Both. Electrons absorb energy and move to a higher energy state, which is unstable, and they fall back down to their ground state immediately, releasing energy as they do.
<span>Molar mass is the mass of a given substance divided by the amount of that substance, measured in g/mol. So probably A.)</span>
The keyword here is gas condenses to a liquid, which mean we're talking about condensation process
The enthalpy energy in condensation process is negative because it releases energy
The entropy in general will also decreases .
Temperature affect this change because it will create free energy if added with this result
hope this helps
