Which of the following is the best thermal insulator APEX

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).
