How can entropy explain formation of soap bubbles

AI Thread Summary
Entropy describes randomness and possible states, but its role in everyday scenarios, like washing hands, can be complex. When bubbles form in the sink, they appear ordered, yet this organization results from the energy input from hand motion. If left undisturbed, bubbles maintain their structure due to surface tension and gas pressure rather than entropy driving them to disintegrate. The restriction of volume and the physical properties of the bubbles play a more significant role in their stability than entropy does. Understanding these interactions highlights the nuanced relationship between entropy and order in physical systems.

I've taken basic college physics and chemistry courses where I learned about entropy and thermodynamics, and I can tell you that I don't know that much :) That's my background.

I understand that entropy is a description of 'randomness' and possible 'states'. When I wash my hands with soap, I wonder how entropy plays a role. When you wash your hands and look at the sink, you'll likely see bubbles aggregating. Now, isn't that a highly ordered state? You can argue that the motion of your hands create such organized state, that energy was created to give order in the system; but if left alone, why don't the bubbles un-form, due to the absence of motion?

Entropy doesn't play a part so much as the restriction of volume. The gas inside the bubble will push at the sides and force the bubble to be the most efficient model because of the bubbles surface tension. Entropy doesn't act as a strong enough force to degrade the optimized design.

Hope I could help.
 
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 '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...
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...
