According to the kinetic theory

a) only particles of matter in the gaseous state are in constant motion

b) gas particles are relatively close together

c) there is no attraction between particles of a gas

d) gas particles lose energy when they collide

The correct answer is option (a).

Explanation:

Kinetic gas theory :

a graduated cylinder.

explanation:

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.
