Which tangible material is the poorest conductor of heat? I know Bismuth and LI-900 Silica are very poor conductors of heat, but I need to know if there are even worse conductors. Best answer will be marked Brainliest.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
