Gas expands under heat so the pressure would rise when a sealed gallon can is heated.

What happens to the pressure of a heated substance?

Generally, as a substance in a sealed container is heated, the pressure will increase. (This is especially true of gases as stated by the combined gas law)


What happen to the gas pressure within a sealed gallon can when it is cooled?

The gas pressure within a sealed can will decrease when it is cooled.


What happens to a sealed bottle full of water if it was heated?

If heated to and above boiling point the pressure in the bottle would begin to rise. Depending on how much it is heated it might either stay like that, or the increased pressure might cause the bottle to burst.


What happens when water is heated in a sealed container?

The steam builds up pressure and once it reaches a certain point, the lid blows off.


What happens to a sealed tin lid when heated?

The air inside the tin will expand when heated causing great pressure on the inside of the can. If the pressure inside the can is greater that the force holding the lid on, then the pressure will force the lid to pop off off the can. have to heat it then and go crazy


What happens to bromine when it's heated?

What happens to bromine gas in a sealed tube when it is cooled and later heatedAnswer:When bromine is cooled and then heated in a sealed container, the bromine juice starts evolving in a gaseous state. It then becomes a gas i.e. bromine gas which is red-brown in color


What happens when a sealed metal container that is holding a gas is heated?

The gas molecules receive energy and start to vibrate. The pressure within the container increases. The container could explode.


Why do tin cans get crushed if cooled after heated and closing is mouth?

Assuming the can can be sealed. When the can is heated the air inside it expands. If the can is then sealed and allowed to cool the air inside contracts which causes the pressure inside to drop. Because the outside air pressure is now greater it crushes the can.


What happens to a gas in a sealed container when the container is heated?

The gas molecules receive kinetic energy and start to vibrate


What would happen if helium was combine with heat energy?

Well, that depends upon the amount of heat energy in question. Nuclear fusion happens at sufficiently high temperature and pressure. Otherwise, you just have hot helium. Like all gas, helium will expand when heated, or in a sealed container, the pressure will increase. With enough heat you can make the sealed container explode.


What happens when you heat a sealed can of air?

The pressure is increasing; at a more high temperature an explosion occur.


If you heat a can and place it into ice water?

if the can is heated, sealed and placed in cold water, then the gas pressure inside the can will be greatly reduced by the cooling effect, and the atmospheric pressure outside will cause the can to crush.


How do seawater boils at 45 degree centigrade?

It wouldn't, unless you put it in a sealed and heated vessel and pumped most of the air out, creating a really low pressure..



A gas held in a 25.3 mL container is heated from 25C to 37C. What is the final volume of the gas?

In a sealed container the volume remain the same and the pressure increase.


Is the volume occupied by the gas in the flask approxmately the same greater or less than before it was heated?

Assuming the flask is sealed - the volume remains the same but the pressure increases


If a tin is filled with hot water and sealed then covered with cold water What causes the tin to become dented?

The outside air pressure dents the tin. The water or air inside a sealed metal container will contract when cooled from the outside (by conduction through the can). When it was sealed, the pressure on the inside was the same as on the outside. But the contraction reduces the pressure on the inside, causing the external air pressure to squeeze the can, and possibly cave it in. This is widely demonstrated in another experiment using dry ice. A sealed gasoline can of about a gallon (4 liters) is placed on a dry-ice bed and cooled until the outside air pressure crushes the can.


What makes popcorn really pop?

Each kernel has a little moisture in it. When the moisture is heated and boils, since the kernel is sealed, it explodes under pressure from the boiling moisture which has no where to go.


Explain why an aerosol can should never be thrown into a fireplace or incinerator?

It will explode with considerable force, causing death and injury. The pressure in the sealed can rises when heated. When it is high enough, the can ruptures.


4 Why is it dangerous to heat a liquid in a distilling apparatus that is closed tightly at every joint and has no vent to the atmosphere?

When the temperature inside a tightly sealed apparatus is heated, the pressure inside increases. It will explode!

Will the pressure in a sealed container change in a pressurized air plane?

Well pressure within a sealed container is defined by the pressure surrounding the container. If the pressure outside is equal to the pressure within the sealed container, there is no positive or negative pressure gradient. If the pressure outside is less than the pressure within the sealed container, there is positive pressure increase within the container. Because air in the higher atmosphere is of lesser pressure than at ground level, bringing a seal container filled at ground level to the higher atmosphere will cause the sealed container to increase in internal pressure. However, you asked what will happened within a pressurized airplane, pressurization within the airplane is meant to prevent the pressure within the cabin from dropping to that of the surrounding environmental pressure. Therefore a sealed container within a pressurized airplane should not change significantly, assuming the container was filled at ground pressure, the pressure which cabins are pressurized to.

The sample is placed in a sealed capillary and heated up to the melting.


What is the pressure of water in a sealed tank?

This depends on the temperature.


Is a tank a pressure vessel?

I guess it depends on whether it's sealed or not. If it's open to the atmosphere how can it be under pressure ? If it's sealed it could be put under (positive or negative) pressure so would be, by definition, a pressure vessel IMHO.
