AI Thread Summary
Collagen binding to bone results in an increase in entropy, despite the appearance of increased order. This counterintuitive phenomenon occurs because the system encompasses more than just collagen and bone; it includes the complex interactions within the living organism and its environment. The overall entropy increases due to the numerous molecular interactions and the dynamic nature of biological systems. This broader perspective on the system allows for greater entropy, even when specific components appear more ordered. Understanding this complexity is essential for grasping the thermodynamic implications of collagen's role in bone structure.

When collagen binds to bone, the entropy of the system increases. Why does the entropy not decrease, since it seems more logical that the entropy decreases since it seems to become more ordered?

The system includes more than just the collagen molecules and the bone that they bind to. Include the entire complex chemical stew that makes up the living organism and its surroundings, and there is plenty of room for entropy increase.
 

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 '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...
