AI Thread Summary
Temperature is defined as the measure of the average kinetic energy of atoms or molecules in an object, reflecting their motion. It indicates how hot or cold something is, with variations in atomic motion contributing to different temperature readings. The concept of temperature can become complex when delving into strict definitions and related phenomena like heat and work. Understanding temperature is essential in various scientific contexts, including thermodynamics. Overall, temperature serves as a fundamental property in physics that quantifies thermal energy.

What is temperature?

How hot something is?

A simple definition would be the amount of motion of atoms, a strict definition gets complicated.

What is temperature?

An object's temperature measures the average kinetic energy of its "jiggling" atoms or molecules. Average because some 'jiggle' fast and some 'jiggle' slow.
 

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...

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...
