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.

The pressure above a liquid in a sealed container is?
Vapor Pressure.
Can liquid nitrogen evaporate from a sealed container?
Do not enclose liquid nitrogen in a sealed container, as this may result in bursting or an explosion due to pressure buildup caused by the evaporation.
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.
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.
If a container is half filled with a liquid and sealed at room temperature and atmospheric pressure then what happens inside the container?
because the other half is not empty it is filled with gas
Is water pressure affected by water temperature?
hardly at all hardly at all, however in a sealed container, the pressure will rise as temp goes up, and near boiling it will go sky high
The pressure above a liquid in a sealed container is?
Vapor Pressure.
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.
Would the boiling point of water be higher or lower on a mountain peakhow would the boiling point be affected in a pressurized system?
The higher the pressure being exerted on the water, the lower the boiling point becomes. Yes the boiling point is affected in a pressurized system. If you put water in a sealed container and kept raising the pressure it will eventually reach it's boiling point without the need of adding heat.
Can liquid nitrogen evaporate from a sealed container?
Do not enclose liquid nitrogen in a sealed container, as this may result in bursting or an explosion due to pressure buildup caused by the evaporation.
What are three possible causes for increase in gas pressure?
Compressing it, heating it (in a sealed container) or adding more gas to a quantity already in a sealed container (which is like compressing it).
Which change results in an increase in gas pressure in a sealed and flexible container?
increase in volume

When boiling water in a can then dipping can into cold water why does the can shrivel up?
Most all items swell somewhat with heat applied. Water does so dramatically. So when a full and sealed container cools, the water retracts in size accordingly. This changes the pressure within the container, so the pressure on the outside is greater and causes it to collapse
As the pressure in a vessel containing water is reduced with a vacuum pump it begins to boil at some point but will it continue to boil if the vessel is sealed after it begins to boil?
If the vacuum pump is on, the water will continue to boil. If the vacuum pump is off as the vessel is sealed, the boiling will stop at a point of equilibrium.
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.
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.
