With the increase of pressure, the boiling point of water

Concept:

• According to ideal gas equation

PV = nRT

• Either we can say that pressure will be directly proportional to temperature if volume kept constant this is the principle used pressure cooker.

Explanation:

• The pressure cooker is based on the principle that the boiling of water increases with the increase in pressure, in a pressure cooker pressure is created by boiling a liquid, such as water or broth, inside the closed pressurized container.
• When we give heat to the pressure cooker then due to an increase in temperature the steam generated in the vessel.
• Due to this generated steam, the pressure inside the vessel increases.
• As the pressure rises, the boiling point at which water is converted into steam also rises above the normal 100⁰C boiling point.
• Hence the higher the pressure, the shorter the cooking time because of an increase in the boiling point of a liquid.
• From this, we can see that as we increase pressure, the boiling point of water will also increase.
