Which example best demonstrates Charles’s law?
2 answers:
<u>Answer:</u>
<em>D. A syringe pulls in air as the plunger is pulled back.</em>
<u>Explanation:</u>
As per Charles’s law
At constant pressure for a given amount of a gas,
Volume is directly proportional to its temperature.
Directly proportional means when one increases the other one too will increase. That is when volume increases temperature too will increase. When volume decreases, temperature too will show a decrease.
Option A tells us that the volume of the hot air balloon increase due to the rise(increase) in temperature as the balloon is heated
Thus the expression is
where k is a constant
When there is a change in the volume and temperature the expression will be
where and
are the initial volume and initial temperature and
and
are the final volume and temperature.

See explanation.
Explanation:
Hello,
In this case, we say that chemical reactions are governed by the law of conservation of mass, which states that matter cannot be neither created nor destroyed by transformed, for that reason, we need to balance chemical reactions in order to ensure all the atoms to be in the same quantity at both reactants and products.
Moreover, equilibrium is defined as such condition at which the concentration of both reactants and products stop changing over the time so they become constant as well as their null reaction rate.
A widely acknowledged reaction is the HABER one which consists on the synthesis of ammonia by using elemental nitrogen and hydrogen:
In such reaction, we have two nitrogens at both reatants and products and six hydrogens at at both reatants and products for us to obey the law of conservation of mass. Furthermore, as the time goes by, nitrogen reacts with hydrogen, nonetheless, they do not react indefinitely, they have a limit that is equilibrium, so their moles stop being consumed and remain unchanged as well as the produced moles of ammonia.
Best regards.
