The boiling point of water can vary based on factors like altitude and atmospheric pressure. At higher altitudes, where the atmospheric pressure is lower, water boils at a lower temperature. This is because the lower pressure makes it easier for water molecules to escape into the air as vapor.
Pressure will be decreased
There is no fixed relative humidity by temperature. There is an absolute maximum, determined by temperature and pressure. At 25 degrees C, air can hold about 23.04 grams of water per cubic meter (g/m3) At 28 degrees C, air can hold about 27.4 grams of water per cubic meter (g/m3). This is about 19.3% more water vapor. *This is based on standard atmospheric pressure. Denser air hold more, thinner air holds less.
Yes, a pure liquid will generally boil at a fixed temperature at a given pressure. This temperature is known as the boiling point, and it remains constant as long as the pressure is constant.

The lower fixed point of a thermometer is typically determined by immersing the thermometer in a mixture of ice and water. This point is known as the ice point, as it represents the temperature at which ice and water coexist in equilibrium under normal atmospheric pressure.
Upper fixed point is the temperature of pure water boiling at normal atmospheric pressure.Lower fixed point is the temperature of a mixture of pure ice and pure water at normal atmospheric pressure. Each thermometer has a scale containing an upper and lower fixed points depending on the use of this thermometer for specific measurements.

The fixed reference points on the Celsius thermometer are the freezing point of water at 0 degrees Celsius and the boiling point of water at 100 degrees Celsius, under standard atmospheric pressure.
The ballon contains a fixed amount of gas producing internal pressure. At the surface, this pressure equals the surface atmospheric pressure. As the balloon rises, the atmospheric pressure drops, allowing the balloon to expand, keeping the internal pressure and external pressure equal. If the balloon is fully inflated at the surface it will burst at higher altitude.
The upper fixed point on a thermometer is the temperature set at 100 degrees Celsius, which corresponds to the boiling point of water at standard atmospheric pressure. This fixed point is used as a reference point for calibrating the thermometer.
upper fixed point is a temperature of stem from water boiling and standards atmospheric pressure lower fixed point is the temperature of pure melting ice.
The lower fixed point in the Celsius scale is 0 degrees Celsius. This point is defined as the freezing point of water at sea level under standard atmospheric pressure.
Why does atmospheric nitrogen need to be converted?
The lower fixed point of a clinical thermometer is the temperature of the ice point (0°C) and the upper fixed point is the temperature of the steam point (100°C at standard atmospheric pressure). These fixed points are used to calibrate the thermometer for accurate temperature measurements.
Well the easiest answer I can think of is to use the ideal gas equation and look at the terms and their effect on pressure. PV=nRT == P=(nrRT)/V, as can been seen from the equation: Pressure is directly proportional to Temperature and inversly proportional to Volume. So you trap air inside a fixed volume container. (Note: not every container will work. The walls of the container must be able to withstand the imbalance between the new inner air pressure and the atmospheric pressure.) Then simple cool the container. If you have gauge fixed to the rigid container (measuring the interior) you will see a drop in air pressure inside the container.
The lower fixed point on the Celsius scale is defined as 0 degrees Celsius, which corresponds to the freezing point of water at standard atmospheric pressure. It serves as one of the reference points for the Celsius temperature scale.
