Consider the energy transfers and transformations that occur when a person rides a bicycle. Describe this process by selecting the correct options from the drop-down menus.

Chemical energy is transformed into energy in the person's muscles.
(kinetic) - answer

Kinetic energy is from the person's legs to the pedals.
(transferred) - answer

Kinetic energy is
thermal energy due to friction when the wheels get warm.
(transformed into) - answer

it is the most commonly accepted one

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.
