The enclosed cabin of a submarine has a volume of 2.4 × 105 liters, a temperature of 312 k, and a pressure of 116 kpa. as people in the cabin breathe, carbon dioxide gas, co2(g), can build up to unsafe levels. air in the cabin becomes unsafe to breathe when the mass of co2(g) in this cabin exceeds 2156 grams. show a numerical setup for calculating the pressure in the submarine cabin if the cabin temperature changes to 293 k

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
