The volume of the container is increased.
barometric
To answer this question you first need to know how big the container is. What is the volume of the container?
Since you have specified a closed container, the amount of gas doesn't change, and the volume that it occupies doesn't change. The only thing that is likely to change is the temperature, and changes in temperature will cause corresponding changes in pressure. And if the pressure gets too high, your closed container is going to explode. So avoid overheating.
increase in volume
The change in pressure is highly affected by altitude.
Change in volume - container getting bigger or smaller with same amount of air; Change in temperature - air gets hotter or colder causing it to expand or contract; Change in density - air is pumped into or out of a fixed container.
The pressure of the container
In a small volume container the pressure is higher.
With gasses, it's a three-way balance between pressure, temperature and volume. If you change one, you affect the other. When you release gas from a container, the the pressure and the temperature drops.
it would change the pressure exerted by the gas in the container.
The boiling point of an element or a substance is the temperature at which the Vapor_pressureof the liquid equals the environmental pressure surrounding the liquid.if we close the container and change the pressure outside the container.. the boiling point will change... why?? how will the solution inside know that the pressure outside the container is changing and it has to now change its boiling point.??
If you increase the volume of the container, and not the gas itself, then the pressure decreases. If you increase the volume of the gas, and not the container, then the pressure increases.
It doesn't change
Heating a gas in a closed container would increase it's pressure. This would happen because when you heat the gas, the particles' kinetic energy increases, making them move faster, and more. They will hit the sides of the container and create pressure.

Yes, it can.

Increased pressure is a physical change, not a chemical change - even if the increase in pressure is itself the result of a chemical process.
