Using context clues, what does the word in bold mean?
-after his eight-mile run, mel was -voracious -and ate everything in the refrigerator.-
a)elated
b)tired
c)hungry
d)energetic

c) hungry

Explanation:

The context clues that help us here are in the rest of the sentence. He went for a very long run, thus expending a lot of energy and calories. While this could also make him tired, the ending piece of the sentence states that he ate everything in the refrigerator. If 'voracious' meant tired in this context, he would have gone home and slept. But he was hungry, so he ate.

the gas pressure p, gas volume v, and gas temperature t are given in the formula:   pv=nrt,

r is the gas constant, and n is the number of gas moles.

if the container is cooled and remains under atmospheric pressure, where r is a constant that does not change, the volume of the container remains the same, the conclusion is drawn that, with all other values ​​unchanged, the number of gas moles n, is decreases.

the right answer is a.
