Suppose that you compare the before/after values of the quantity in Part 1 and they are not exactly the same. In this procedure, what could be responsible for the difference?
Group of answer choices
If the tube is not perfectly sealed, some gas will leak out, which changes the number of gas molecules (), so that the ratio isn't exactly constant.
When the air in the plunger is compressed, it absorbs additional heat from the environment while the measurement is being made. Since this is not accounted for, it could cause to not be constant.
If any heat leaves the compressed air when it heats up, it would go into the environment (the room), and that energy is not recovered on decompression, so the ratio wouldn't be constant.
