Will Mixing Hot Air and Steam in a Sealed Cylinder Change Pressure?

AI Thread Summary
Mixing hot air and steam in a sealed cylinder will affect pressure due to the differing temperatures and properties of the gases involved. The initial conditions, with hot air being significantly hotter than steam, suggest that the pressure will change as the gases mix. Calculating the exact pressure change requires using steam tables and the ideal gas equation, as the interaction between the gases is complex. If hot and cold air are admitted and allowed to mix after sealing, the pressure dynamics will also vary based on their respective temperatures and volumes. Overall, the scenario presents a nuanced thermodynamic challenge.

Hi, everyone!

I have a question: if we quickly fill a cylinder with steam from one end and with hot air from another end, both at atmospheric pressure and equal volume, with hot air 4 times hotter than steam, and then immediately seal that cylinder -- will pressure change as steam and hot air mix together or not? Let's say that cylinder is insulated and no vacuum happens because of external cooling. And what's going to happen with pressure if we admit hot and cold air respectively and let them mix after sealing?..

Welcome to pf!

Why don't you pick some values and try using a steam table and the ideal gas equation to solve this? I don't think it has a simple answer.

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...
