Which description of salt is a physical property?

salt is dull and brittle and conducts electricity when it has been dissolved into water, which it does quite easily.

Explanation:

transparent and colourless in crystalline form- rather like ice.

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.
