Question

the diagram shows represents three balloons, each containing an identical volume of oxygen, hydrogen, and nitrogen. when the three balloons are heated equally, which group correctly shows their new volumes? a) diagram of three balloons with o, h, n b) diagram of three balloons with o, h, n c) diagram of three balloons with o, h, n d) diagram of three balloons with o, h, n o a o b o c o d

Explanation:

Step1: Recall Charles's Law

According to Charles's Law, for a given mass of gas at constant pressure, $V\propto T$ (where $V$ is volume and $T$ is temperature). When the three balloons (containing oxygen, hydrogen and nitrogen) are heated equally, assuming the pressure remains constant, the volume of each gas will increase by the same proportion since they start with identical volumes and experience the same temperature - change.

Step2: Analyze the options

Option a shows no change in volume. Option b shows different volume - changes for different gases which is incorrect as per Charles's Law under the given conditions. Option d shows a decrease in the volume of nitrogen which is incorrect. Option c shows all three balloons increasing in volume equally which is consistent with Charles's Law.

Answer:

C
