I kind of wish that it was explained to me this way a quarter of a century
ago, when I was struggling with thermo & physics.

Don't confuse heat and temperature. Temperature measures average kinetic
energy of molecules moving around in a sample - but the sample can be
arbitrarily small. Heat is more like the product of temperature and mass.

Take a piece of aluminum foil and a cast-iron skillet in the oven at 600C.
You can pick up the foil - it *was* at 600 C, but it's so light that it
can't transfer enough heat to your hand to damage you before it cools down.

Don't pick up the cast-iron skillet. Lots more mass, lots more heat,
definitely can damage you.

This is a lot like the speed vs. momentum discussion a few days back. 
One atom at high speed = high temperature, but not much heat. A locomotive
at high speed = high temperature, lots of mass, lots of heat -> dangerous.

So the wizard will have to crank up the volume *twice* - once to get higher
temperature, then again to get it over a larger mass (and really, it's the
*product* of the two that he should have to spend) - at least if magic
converts linearly to measurable heat energy.
