Question

Molecules in a ___________ vibrate in a fixed position and do not move around much.

solid
liquid
gas
plasma

During photosynthesis, energy is absorbed from the sun by plants to create sugar. Which type of process is this?

combustion

endothermic

exothermic

spontaneous

Answer 1

The first one should be simple to find out

We can cross off plasma right off the bat. I'd say this bc their molecules move around freely and randomly

Liquid- Molecules are kinda close together they do have space available to move around (not in place)

Gas- Molecules are hugely separated and scattered and have space to move around (not in place)


The last answer option left is (Solid), I'd say it correct bc the molecules of a solid vibrate in one place and they don't so do that very often

We would need to look at the definition of each word



Combustion- the process of burning something.

Endothermic- (of a reaction or process) accompanied by or requiring the absorption of heat.

Exothermic-(of a reaction or process) accompanied by the release of heat.


Spontaneous-performed or occurring as a result of a sudden inner impulse


I think we can cross off A.(the process of burning something.) bc no were in the process of photosynthesis does it talk about the burning of a plant, we can also cross off answer option D.(Spontaneous) has honestly nothing to do with photosynthesis


This leaves answer options B.(Endothermic) and C.(Exothermic)


(We can easily use "context clues and the definitions we found" to answer the question)


"energy is absorbed from the sun"

Basic knowledge the sun is a big firey star that has a lot of heat energy. We say it packs a lot of "thermal energy" to be more specific.

So in the process of photosynthesis plants absorb thermal energy from the sun to create sugar.

"Endothermic- (of a reaction or process) accompanied by or requiring the absorption of heat.

Exothermic-(of a reaction or process) accompanied by the release of heat."


Endothermic is the process of absorption of heat-(basically thermal energy)

and


Exothermic energy is the process of releasing thermal energy.


So your answer would be B.(Endothermic)

A.(Solid)



Question 2.


B.(Endothermic)
