No, the external environment does not affect the boiling point of a liquid inside a pressure cooker. Since the liquid is sealed away from the air, it is not affected by ambient air pressure or humidity.
Pressure & Temperature :) Apex
The outdoor ambient temperature significantly influences head pressure in refrigeration and air conditioning systems. As the temperature increases, the heat absorbed by the refrigerant rises, leading to higher head pressure due to increased vapor pressure in the condenser. Conversely, lower ambient temperatures can reduce head pressure as the refrigerant condenses more efficiently. Maintaining optimal head pressure is crucial for system efficiency and performance.
Changing water pressure can affect the boiling point because it alters the equilibrium between liquid and vapor phases. Increasing pressure raises the boiling point, as more energy is needed to overcome the higher pressure. Decreasing pressure lowers the boiling point, as it requires less energy to vaporize the liquid.
The boiling point of water depends only on pressure, not ambient temperature. The only correlation between climate temperature and boiling point would come about from the fact that cold climates in temperate parts of the Earth are usually at higher elevations than warmer climates and therefore have lower atmospheric pressure.
Increasing pressure hinders the ability of two fluids with different boiling points to separate. Reducing pressure does the opposite and makes the fluids easier to separate based on boiling point.
Boiling point is where the vapor pressure of a liquid equals the ambient pressure. The closer you are to the boiling point, the more driving force there is for the liquid to evaporate until it saturates the surrounding air.
Vapor pressure of the liquid, ambient pressure, temperature, and surface area of the liquid.
There is a direct relationship between the temperature at which water boils and the air pressure on it. Higher pressure, higher boiling point. Lower pressure, lower boiling point.

Because the pressure could affect the temperature at which the water boils
The boiling point of a liquid depends on the pressure applied to it: higher pressure raises the boiling point and lower pressure decreases it. By reporting the boiling point along with the pressure, it allows for accurate comparison and reproducibility of experimental results, as different pressure conditions can affect the boiling point.
Changing water pressure can affect the boiling point because it alters the equilibrium between liquid and vapor phases. Increasing pressure raises the boiling point, as more energy is needed to overcome the higher pressure. Decreasing pressure lowers the boiling point, as it requires less energy to vaporize the liquid.

At low pressure the boiling point is lowered and inverse.
The density of water does not directly affect its boiling point. Boiling point is primarily determined by the atmospheric pressure, which influences the temperature at which a liquid changes into a gas.
Ambient temperature might affect the readings of the resistance value you would measure because the resistance of some materials changes with the temperature.
