Mabel conducted an experiment as shown in the diagram below. in each set-up, a conical flask was filled with identical volumes of air at different temperatures. the set-ups were then left until the air in the flasks reached room temperature. state if the red-coloured oil drops in each set-up will increase, decrease or remain at the same height at the end of the experiment. explain your answer in terms of heat gain or heat loss.
(the pic is suggested ans, i don't understand why since i think it should be the opposite)

a patient chooses to not take a beneficial medical treatment.

explanation:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
