Amateur physics here, how is entropy linked to the universe?

AI Thread Summary
Entropy is a fundamental concept in both chemistry and physics, representing the degree of disorder or randomness in a system. In physics, it is often associated with the second law of thermodynamics, which states that the total entropy of an isolated system can never decrease over time. This principle implies that natural processes tend to move towards a state of maximum entropy, or equilibrium. Understanding entropy in the context of the universe involves exploring its implications for energy distribution and the arrow of time. Further research into the various meanings of entropy can provide a deeper insight into its applications across different scientific fields.

I learned about entropy is chemistry, can someone please explain how this term is used in physics? Thanks.

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...
