Induction Heating Ice: How Does it Work?

AI Thread Summary
Induction heating of ice is likely a case of dielectric heating rather than actual induction heating. Dielectric heating works by exciting dipoles in polarized molecules, such as water and fats, while induction heating uses eddy currents in metals. The discussion raises questions about the glowing effect observed in the ice, with some suggesting it could be glass instead. The video linked in the discussion remains a point of curiosity, prompting further investigation into the phenomenon. Overall, the mechanics of heating ice through these methods warrant more exploration and experimentation.

Does anybody know how this works?

Synetos...what's the source of the video??

I am not positive what is happening...that IS a fascinating little video...

I suspect this is an example of dielectric heating,
perhaps at frequencies different from a typical microwave oven?

not actual INDUCTION heating...
http://en.wikipedia.org/wiki/Induction_heating

The basic difference is that dielectric heating as in a microwave oven heats via dipoles...polarized molecules especially in water but also in fats and ice to lesser degrees... while induction heating accomplishes the transfer of electromagnetic energy via eddy currents in metals...especially ferromagnatic metals...

I have no idea why the ice appears to "glow" internally...
 
Are you sure it is ice? I would think that glass is more likely. Seems like an episode of Mythbusters waiting to happen.
 

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...
