What has thermal energy but not heat? (and vice versa)

AI Thread Summary
Thermal energy refers to the energy of motion at the particle or atomic level, while heat is defined as the transfer of that energy. The discussion raises questions about scenarios where thermal energy exists without heat transfer and vice versa, suggesting that these concepts are often misunderstood. It is noted that the questions may be poorly phrased and could be better articulated through the lens of the first law of thermodynamics. Additionally, a rephrased question regarding the requirements for a change in angular momentum is proposed for clarity. Understanding these distinctions is crucial for grasping fundamental thermodynamic principles.

This isn't homework, so i thought it could go here.

1) What has thermal energy but not heat?
2) What has heat but not thermal energy
3) What effects angular momentum?
 
Science news on Phys.org
are these questions posed by a book or teacher?

for 3) i would rephrase the question as "what is required for a change in angular momentum". I think that might be what the question is after.

If I'm on the right track, 1) and 2) are also poorly phrased questions that can be answered by considering the first law. I might be off track though.
 
It's from a teacher for on a test.

I know thermal energy is the energy of motion from particles or atoms. And that heat is energy transfer.
 
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...
