Boiling point of water in a closed container

AI Thread Summary
In a closed container, the boiling point of water is determined by absolute pressure, not gauge pressure. With a gauge pressure of 101 kPa, the absolute pressure is 202 kPa, which raises the boiling point above 100°C. The boiling point increases as pressure increases, so it will be higher than 100°C in this scenario. Therefore, the boiling point is influenced by the absolute pressure of the system. Understanding this distinction is crucial for accurate calculations in pressurized environments.

Hi all, for a closed container with water under pressure in it, let's say GAUGE PRESSURE of the container is 101 kPa, what will the boiling point of water in that vessel be? Will it be 100 deg C, or will it be 120 deg C because the ABSOLUTE PRESSURE of the water in that vessel is 202kPa? Basically I wanted to see if boiling point is dependent on ABSOLUTE PRESSURE or GAUGE PRESSURE!
Thanks!

Well, hopefully you know that when the absolute pressure is 1 atm (gauge pressure = 0, relative to 1 atm), the boiling point is 100 C.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Free fall of person in a sled to direct horizontal motion by atmospheric resistance'

Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
