In this website, you mention that *Energy and entropy are always well  
defined, even in cases where heat is not.*

Perhaps, you should consider to revise this statement? There is still  
NO good definition on energy!

Letting the students to argue on the definition of heat could sharpen  
their concept too.

By the way, Halliday defined Heat as "the energy that is transferred  
between a system and its environment..." So, it seems that he is also  
another advocate for "Heat is a noun". :-)
