Oh, dude, you bet it will! When you're cruising at 35,000 feet, the pressure inside a sealed container will definitely change because the air pressure outside the container is lower due to the higher altitude. So, like, if you're bringing a bag of chips on board, don't be surprised if it looks like it's about to pop open mid-flight!
What else can I help you with?
Why is it dangerous to heat a sealed or presssurised can?
heat causes any substance to expand. If enough heat is applied to change a substance from a liquid to a gas, it expands exponentially. In a sealed or already pressurized can, this can cause pressure to build until the can cannot contain it any more and explodes like a bomb. This can send shrapnel from the can flying a good distance, and can cause serious injury if it hits anyone.
Why would a sealed container of air be crushed after being frozen?
A sealed container of air would be crushed after being frozen because as the pressure decreases, the temperature also decreases. The air molecules inside of the sealed container shrink when it is frozen. The colder the air, the lower the temperature.
Can liquid nitrogen evaporate from a sealed container?
Yes, liquid nitrogen can evaporate from a sealed container due to its low boiling point of -196°C. The pressure will increase in the container as the liquid nitrogen evaporates, eventually leading to a rupture or explosion if the container is not designed to handle the buildup of pressure.
How would mass change if you place a burning candle in a sealed container?
The mass would remain the same. In a sealed container, the products of burning (such as soot and water vapor) are not able to escape, so the mass inside the container would stay constant due to the law of conservation of mass.
If the pressure in a sealed container is reduced can boiling point of a fluid be also reduced?
Yes. You can, for example, boil water at room temperature if you apply a vacuum pump to the container. However, if it was ONLY a sealed container (reduce the pressure and then take the vacuum pump away), the vapor increases the pressure and the whole thing comes to equilibrium and stops boiling.

If a liquid is sealed in a container and kept at constant temperature how does its vapor pressure change over time?
If a liquid is sealed in a container and kept at a constant temperature, its vapor pressure will initially increase until it reaches a constant value, known as the equilibrium vapor pressure. At this point, the rate of evaporation of the liquid equals the rate of condensation of the vapor, resulting in no further change in vapor pressure over time. This equilibrium is maintained as long as the temperature remains constant and the container remains sealed.
Which change results in an increase in gas pressure in a sealed and flexible container?
Increasing the temperature of the gas will result in an increase in gas pressure in a sealed and flexible container, as the gas particles will move faster and collide more with the container walls, exerting a greater force per unit area.
What is the effect of a decrease in volume of a sealed container of gas with no change in temperature?
A decrease in volume of a sealed container of gas with no change in temperature leads to an increase in pressure according to Boyle's Law. This is because the gas molecules are confined to a smaller space, resulting in more frequent collisions with the container walls.
Why shouldn't sealed containers be heated without being punctured?
Sealed containers should not be heated without being punctured because the heat causes the contents to expand, leading to increased pressure inside the container. If the pressure exceeds the container's strength, it can result in an explosion, posing safety hazards such as burns or injuries from flying debris. Puncturing the container allows for the release of built-up pressure, making heating safer. Always prioritize safety when handling pressurized materials.

Why will a container of gas explode when heated?
Increasing the number of moles of gas, decreasing the volume of the container, or iIncreasing the temperature could cause a rigid container of gas to explode.
If the pressure in a sealed container is reduced can boiling point of a fluid be also reduced?
Yes. You can, for example, boil water at room temperature if you apply a vacuum pump to the container. However, if it was ONLY a sealed container (reduce the pressure and then take the vacuum pump away), the vapor increases the pressure and the whole thing comes to equilibrium and stops boiling.
Why don't liquids evaporate when sealed?
When a liquid is sealed in a container, the vapor pressure of the liquid increases inside the container until it reaches equilibrium with the liquid. At this point, the rate of condensation of vapor back into the liquid is equal to the rate of evaporation, resulting in no net change in the liquid level. The container essentially traps the vapor, preventing further evaporation.
Why does air pressure in a cars tire increase after a long drive?
As you drive, the friction of the road and the flexing of the tire increases the tires temperature. When you increase the temperature of a gas in a sealed container the pressure goes up.As you drive, the friction of the road and the flexing of the tire increases the tires temperature. When you increase the temperature of a gas in a sealed container the pressure goes up.
