The pressure inside a heated sealed vessel refers to the force exerted by the gas or liquid contained within the vessel on its walls. This pressure is due to the collisions of the gas or liquid molecules with the walls of the vessel.
According to the ideal gas law, the pressure of a gas inside a sealed vessel is directly proportional to its temperature. This means that as the temperature increases, the pressure inside the vessel also increases.
The pressure inside a heated sealed vessel can be affected by the temperature, volume, and amount of gas or liquid present inside the vessel. Additionally, the type of gas or liquid and the strength of the vessel walls can also impact the pressure.
The pressure inside a heated sealed vessel can be measured using a pressure gauge or a manometer. These instruments measure the force exerted by the gas or liquid on a small area and convert it into a pressure value.
If the pressure inside a heated sealed vessel becomes too high, the vessel may rupture or explode, releasing the gas or liquid contained within. This can also cause damage to the surrounding area and pose a safety hazard.
