Definition1/12
To put it in simple terms, all of the energy that would normally
increase the temperature of the object, is being used to convert
the object from one phase to another.
Once the object has completely changed to the new phase, the
energy is not needed for phase change and raises the temperature of
the object.

is the rate constant and m and n are the "order" with respect to
each reactant. m and n must be determined experimentally and may or
may not be the same as the coefficients a and b.

Air
(Explanation): water has a high specific heat capacity, but it can boil. stone (😂) also is a good thermal insulator, but it can get really hot. Metal is a very good thermal conductor, so it is definitely not that. Therefore, air is the best (its also really hard to boil).
