Tanks of compressed gas must be kept away from heat sources. if a compressed–gas tank is heated too much, it may explode and cause a great deal of damage. which of the following best explains why a compressed–gas tank can explode if it is heated? a. as the gas gets hotter, the molecules gain energy and move farther apart, causing the gas to expand. b.as the gas gets hotter, the molecules expand, causing the gas to exert more pressure. c.as the gas absorbs heat, the molecules break apart, increasing the volume of the gas. d.as the gas absorbs heat, the molecules move more quickly, making the gas more corrosive.

Ответ:
The answer to this question is A. As the gas gets hotter, the molecules gain energy and move farther apart, causing the gas to expand. This is because, whenever you heat a substance, (solid, liquid, or gas), the molecules in the substance will always move more rapidly causing the substance to expand and the molecules to move further away from one another.

Explanation:
From the question awe are told that
The distance between the two boats are 46 m
Now we are told that a the time the Jenny's boat is at a crest,Melissa's boat is at its lowest point, and there are 4 additional crests between them which can be mathematically represented as
Number of wavelength = 4 + 0.5(this accounts for the difference in position crest and lowest point)
= 4.5
Now the wavelength of the water is
