A sealed bag of vegetables can expand due to the buildup of gas produced by bacteria present inside the bag. This gas is produced as a result of the vegetables undergoing fermentation, which produces carbon dioxide as a byproduct. If the bag is not properly vented, the trapped gas can cause the bag to expand.
The air in the sealed bag has nowhere else to go so it heats up. When it heats up it creates a good condition for bacteria to multiply and eventually you get the disgusting green stuff we all know and *hate* as mould.
Mold grows faster on a counter compared to in a sealed bag because mold requires oxygen, moisture, and a food source to thrive. A bag restricts airflow and moisture, slowing down mold growth compared to a moist and exposed counter surface.
Agar plates should be disposed of in biohazard waste bins to prevent contamination and following appropriate safety protocols. Ensure that the plates are sealed in a plastic bag before disposal to minimize the risk of spreading any potential contaminants. Contact your laboratory or institution for specific guidelines on the disposal of agar plates.
The solution in the bag is hypotonic compared to the solution in the beaker. This is because the bag has a lower concentration of solute (2%) compared to the beaker (10%), so water will tend to move into the bag to equalize the concentrations, causing the bag to swell.
A blind bag is a type of packaged product, typically in the form of a small bag or box, that contains a surprise toy or collectible figure. The contents are not visible from the outside, hence the term "blind," as the buyer does not know which specific item they will get until they open the bag. Blind bags are popular among children and collectors for the element of surprise and mystery.
the temperature of gas changes (APEX) :)
When a bag of vegetables is heated, the water content within the vegetables turns into steam, causing an increase in pressure inside the bag. Additionally, the heat can cause gases produced from the vegetables to expand. If the bag is sealed and unable to vent this steam and gas, it will inflate, leading to the observable expansion. This effect is similar to how a sealed container can bulge when heated.

The temperature of the gas changes.
The ideal gas law states that as altitude increases, air pressure decreases. This lower pressure causes the bag of chips to expand because there is less external pressure pushing on the bag. The gases inside the bag expand to fill the increased volume.
the bag inside the bag would expand D:
Since tornadoes generate low pressure a sealed bag would expand inside of one.
the bag inside the bag would expand D:
The sealed bag of chips would likely expand or burst due to the increase in temperature and pressure caused by the sun's heat. The heat can cause the air inside the bag to expand, leading to possible breakage or leaks in the packaging.
That would surely depend on the amount of air, as well as the strenght and flexibility of the bag.
the higher the altitude, the less pressure there is inside the bag. Check out Bole's law
Just like water expands to ice..
