Answer: B) there is a decrease in kinetic energy and the molecules get closer together.
Explanation: Kinetic energy is directly proportional to temperature, thus as temperature decreases, kinetic energy also decreases.
Gas is the state of matter in which particles are very loosely bound and hence can easily move past one another very easily and have highest kinetic energy.
Liquid is the state of matter in which particles are loosely bound and hence can move past one another easily and have high kinetic energy.
Solid is the state of matter in which particles are tightly bound and hence can not move easily and have low kinetic energy.
Thus on moving from gaseous to solid state, the kinetic energy decreases and the molecules get closer together.
Answer:
d. less than 100% of the energy captured from sunlight is transformed into potential energy in the form of a hydrogen ion gradient and then into potential energy in the form of covalent bonds
Explanation:
Photosynthesis is process utilized by plants, several bacteria and protists to convert the light energy to chemical energy. So they utilize the photosynthesis as the powerhouse for the energy production. Heterotrophs like human that cannot synthesize their own food, use this converted form of energy by autotrophs.
During the light reaction of photosynthesis the photons from light are absorbed by photosystem I and II. These photons excites the electrons which flow through the electron transport chain from higher potential to lower potential. These electrons release the energy while moving from higher potential to lower potential which is utilized by H+ pump to pump the H+ to lumen of plastids from stroma and of course not the 100% energy is utilized some of the energy dissipates. . So this process causes the accumulation of high potential H+ ions across the membrane. These H+ ions are utilized for the production of ATP by ATP synthase complex when they flow back to lower potential across the membrane through ATP synthase complex.
The ATP and NADPH produced from light reaction are utilized to combine carbon molecules during dark reaction. The covalent bond is used to combine the carbon molecules and we know that combining carbon molecules stores energy in the form of covalent bond.
