AI Thread Summary
A liquid in a vacuum has a lower boiling point than at atmospheric pressure due to reduced external pressure. Thermal decomposition, or thermolysis, occurs when heat causes a chemical substance to break down. While it is questioned whether creating a vacuum could lower the decomposition point of water, the consensus is that it would not be significant compared to standard pressure. The temperatures involved in thermal decomposition are generally much higher than those affecting boiling points. Therefore, the effects of a vacuum on decomposition are minimal.

A liquid in a vacuum environment has a lower boiling point than when the liquid is at atmospheric pressure



Thermal decomposition, or thermolysis, is a chemical decomposition caused by heat.
Water, when heated to well over 2000 °C, decomposes to its constituent elements:

could a a vacuum be created to lower the decomposition point?

No, I do not believe so. Or at least it won't be significant when compared to standard pressure as those temperatures u ~= h.
 

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
