You pop the bag open and capture the air
The mass of the bag with air will be the sum of the mass of the bag itself and the mass of the air inside it. The mass of the air can be estimated by knowing the dimensions of the bag and the density of air at the given conditions.
The bag can pop open as the air inside expands.
The empty potato chip bag was hungry
You can find the answer on the back of the bag on the nutrition facts. Look down and find protein and look to your right and it will have a number. That's how much protein is in a bag of potato chips. Sometimes different brands have different amounts of nutrition is in the bag. That's why you need to look for yourself!
To measure the density of the empty school bag including the air in the bag, you should be able to simply weigh it, and measure its dimensions, and calculate the density, which is weight divided by volume. Bags have a more or less rectangular shape, so the volume is simply length times width times height. If you want to measure the density of the material from which the bad is made, that is a little more complicated, and might require you to squeeze the bag into some kind of compact, easily measured shape, that does not contain air.
The weight of a bag half full of air would depend on the size and material of the bag, but it would be very light. A bag filled with air would also be very light, as air has a low density. The weight of the air itself would be negligible compared to the weight of the bag.
Air Expands When Heated
Yes, rodents can chew through a potato chip bag.
the liters of water in a bag of potato chip is 2 liters
Potato chips get stale when exposed to air because they absorb moisture from the air, which makes them lose their crispness. The oils in the chips also oxidize when exposed to air, causing them to become rancid and lose their flavor.
Generally not, but if air is enclosed in the bag making density less than water then it may floats.
It will vary depending on the size of the bag.
