I can't exactly answer this question because no image of the notation was given. In order to help you, I would just tell how the notation is to be interpreted.
The general notation is shown in the attached picture. E stands for any element in the periodic table. Y stands for the atomic number of the element, or the number of protons in the nucleus. X stands for the mass number, or the number of neutrons and protons in an element. The Y and the atomic number of element E must coincide. You can use the periodic table as a guide.

From the ideal gas equation,
where n is number of moles, R is Universal gas constant, P is pressure, V is volume, and T is temperature of the gas.
The pressure and volume are inversely proportional to each other at constant temperature and number of moles.
Hence, on decreasing the pressure, the volume will increase.
As the hiker reaches a height of a mountain, the pressure would decrease which results in the reestablishment of equilibrium between gas molecules thus resulting in pushing of bag outwards.
Hence, the bag will expand as the hiker reaches the top of the mountain.
