Final answer:
The student seems to be conducting a practical demonstration of Charles's law. Accurately measuring the volume of air near 100°C using a beaker on a hot plate involves noting the change in the height of the air column in the tube. The expansion of the air when heated shows the direct proportionality between gas volume and temperature.
Explanation:
The question appears to be asking for guidance regarding measuring the volume of air near 100°C using a beaker and a hot plate. It's crucial here to note that the volume of air will expand as its temperature increases.
To accomplish this task, first, set up the beaker with the tube and thermometer as described. The volume of the air can be approximated by observing the initial position of the air in the tube and then comparing it to its position after heating. When the air is heated on the hot plate to near 100°C, the air will expand and the tube's height will increase. You can measure this change in height to determine how much the volume of air has increased.
It must be noted that it is a practical demonstration of Charles's law, which states that given a quantity of gas at constant pressure, its volume is directly proportional to its temperature.
