the number of gas molecules changes
The pressure inside an oxygen tank changes due to the release of oxygen gas as it is used. As the oxygen is depleted, the volume of gas decreases, leading to a drop in pressure. Conversely, filling the tank with more oxygen increases the pressure inside.
When you conduct the hot soda can in cold water experiment, the sudden change in temperature causes the air inside the can to cool and contract, creating a lower pressure inside the can. This lower pressure causes the can to be crushed or implode due to the higher pressure of the surrounding atmosphere pushing on the can.
Assuming constant amount of gas and temperature, pressure will increase as volume decreases. Conversely, pressure will decrease as volume increases. If you squeeze on a filled balloon, the volume decreases. The pressure of the air on each square inch of the balloon increases, which causes it to eventually pop if the pressure gets too high. Assuming constant amount of gas, a temperature change will already change the volume of the gas. As temperature rises, the gas expands, causing more pressure to be exerted on the balloon. Assuming constant temperature, adding more gas also increases the volume and thus increases the pressure.
When a can with boiling water is placed in cold water, the temperature difference causes the air inside the can to rapidly cool and contract. This decrease in pressure inside the can creates a pressure difference between the inside and outside, leading to the can imploding as the external pressure crushes it.
When a closed can is heated, the molecules inside the can gain energy and move faster, leading to an increase in pressure. This happens because the increase in temperature causes the molecules to collide more frequently with the walls of the can, exerting more force and increasing the pressure inside.

When the hot air inside the bottle cools down in the freezer, it will contract and decrease in volume. This decrease in volume causes the pressure inside the bottle to decrease, leading to a change in its shape. The bottle may collapse or deform as a result of the reduced pressure.
The air pressure inside the bottle will increase as more air is filled up inside. This is because the air molecules are compressed, resulting in higher pressure.
When an empty tank is filled with air, the air molecules move into the tank and exert pressure on the walls of the tank. This increases the air pressure inside the tank and causes the tank to become pressurized.
A balloon inflates when it is filled with a gas, such as helium or air, creating pressure inside the balloon which causes it to expand. The gas molecules inside the balloon push against the walls, causing it to stretch and increase in size.
As the helium-filled balloon rises into the atmosphere, the surrounding air pressure decreases while the pressure inside the balloon remains the same. This causes the helium inside the balloon to expand, making the balloon increase in size. Eventually, the balloon will reach a point where the difference in pressure between the inside and outside of the balloon will be equal, and it will float at that altitude.
Because of the pressure in the higher atmosphere is much lower than the pressure where it was filled. This causes the pressure inside to expand the balloon up to and past the bursting point. Most likely the tip of the troposphere.
The pressure inside an oxygen tank changes due to the release of oxygen gas as it is used. As the oxygen is depleted, the volume of gas decreases, leading to a drop in pressure. Conversely, filling the tank with more oxygen increases the pressure inside.
The elastic contraction of the rubber in the balloon's membrane causes the pressure in the air inside an inflated balloon. When you inflate a balloon, you have to expand the latex of the balloon, which stretches when filled with air from a pressure of 760 mm Hg to as high as 840 (about 10% higher than standard atmospheric pressure). If you inflate a non-elastic mylar balloon, it takes no effort: the air inside is at the same pressure as the air outside.
When you conduct the hot soda can in cold water experiment, the sudden change in temperature causes the air inside the can to cool and contract, creating a lower pressure inside the can. This lower pressure causes the can to be crushed or implode due to the higher pressure of the surrounding atmosphere pushing on the can.
It causes the Bourdon tube to straighten.
