Temperature due to translational energy of molecules?

AI Thread Summary
Temperature is fundamentally linked to the kinetic energy of molecules, which includes vibrational, rotational, translational, and electronic motion. The discussion clarifies that while moving an object involves macroscopic motion, it does not affect the random motion of the molecules within it. Therefore, the average translational kinetic energy of the molecules remains unchanged, and thus temperature is not influenced by the object's movement. The key takeaway is that temperature specifically relates to the random motion of molecules, not their overall translational movement as a macroscopic entity. Understanding this distinction is crucial for grasping the concept of temperature in thermodynamics.

Hi there,

Ok from my lectures: Temperature is due to the Kinetic energy of molecules. Kinetic energy can be due to vibrational, rotational, translational and/or electronic motion.

Now when you move an object from one place to another, aren't the molecules undergoing a nett translation (granted it's macroscopic but still there's a velocity)? So isn't there temperature involved here (however tiny)-not counting friction !

Thanks!
:)

No. Temperature is a measure of the average translational KE of molecules as measured in the center of mass frame of the system. (The macroscopic motion of an object doesn't effect the random motion of its molecules, which is what temperature relates to.)
 
Thank you for the prompt reply Doc Al!
 
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...
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...
