A propane torch is lit inside of a hot air balloon during preflight preparations to inflate the balloon. Which condition of the gas remains?Volume, temperature or pressure?

pressure

Explanation:

the gas is changing because of the torch being lit inside the hot air balloon which make the volume change when the hot air balloon get put up

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
