Question

How heat is scalar and why

Answer 1

${ \red{ \underline{ \huge{ \mathfrak{answer}}}}}$

Scalars have magnitude, vectors have magnitude and direction. Heat is an aggregate measure of the amount of energy stored in a system of particles (a single particle doesn't have a temperature), but it doesn't point in any particular direction
