Quando colocamos dois béqueres, um com água quente e outro gelada, ambos com mesmo volume; e dentro deles colocamos um comprimido efervescente; em qual deles ocorre a reação mais rapidamente? O que podemos concluir a respeito?

b would be the answer

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

d) physical means can be used to separate the components of air.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
