two buckets of water has twice the heat content as one bucket of water even though they're all at the same temperature.

Yes, intensive property vs extensive property.

What the guy above said. Temperature doesn't go with quantity - look uo "intensive" variable. Also, kelvin is a spooky unit, consider it to be the same as energy, there is only the arbitrary Boltzmann constant in the way. This bts. Makes entropy unitless, as it should be. Its a combinatorical quantity.

change of phase..

and heat can be used to do work

>Is this because of both the P and V changing so that T can remain constant in the ideal gas law?

yes

Don't think of heat so linearly. Remember that heat is just the acceleration of the particles of the substance in question. Therefore, cold would be the particles slowing down.

You're defining temperature wrong, at least for your purpose. "Temperature" is just the measure of a system's tendency to lose or gain heat. Actually, temperature is defined as: T=(dU/dS), where the derivatives are actually partial derivatives. What does this mean practically? It means that the temperature is the slope of the graph of internal energy vs. entropy. A (closed) system's internal energy can be changed two ways: Through P-V work, or by adding/removing heat. Now, there's a famous thermodynamic identity that you better learn if you want to stop being a retard, which is: dU= TdS - PdV. If we do a little algebra, we see that as long as you can hold the system's entropy constant, the temperature will not change. I leave that to you as an exercise.

Doesn't even exist IRL, why do we teach this? The heat engine world is not filled with unicorns and sunshine it is a grim world of 30% efficiency

Because virtually all real thermodynamic work is done as perturbations with respect to the ideal case.

You will learn this when you're older.
