A student observes that flowers in a greenhouse have a very sweet smell. The student explains that these flowers are probably pollinated by bats. Which of these additional observations would strengthen this explanation? A The flowers are open at night and closed during the day. B The flowers continue to bloom for two weeks. C The flowers are brightly colored. D The flowers produce many small seeds.

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.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
