It is definitely a molecule
Answer:
depend on nature of matter
Answer:
Through oxidation of food materials
Explanation:
When living organisms eat, they ingest complex organic food materials. As these food materials enter the body, the process of digestion begins.
Enzymes in the body, located at different parts of the gastrointestinal tract see to the breakdown of these complex food materials ingested. The oxidation of these complex food materials lead to the release of the chemical potential energy stored in them.
Answer:
It is (A.) Gases have the highest kinetic energy, followed by liquids, and then solids
Explanation:
<u>Gases have high kinetic energy</u> because their particles are far apart from each other and have a negligible force of attraction, whereas <u>Liquids have the high force of attraction as compared to gases so they have less kinetic energy than gases</u>, and <u>Solids have the high force of attraction between their particles</u> because of that its molecules are closely packed, therefore
<u>Gases have the highest kinetic energy,</u>
<u />
<u>Followed by Liquids,</u>
<u />
<u>Then finally, Solids with the lowest kinetic energy.</u>
Answer: increased
Explanation:
Powdered zinc has a greater surface area than zinc granules. If the same mass of zinc and volume of acid is used, it will be observed that the powdered zinc will react faster since it provides a greater surface area for reaction compared to zinc granules. The greater the available surface area of reactants, the greater the rate of reaction. Higher surface area means that more particles are available for reaction.
