The Kinetic Molecular Theory (KMT) is discussed in this lesson, and it helps us understand the behavior of gases. From what we learned, which of these statements are consistent with KMT? A. Due to the large amount of empty space between gas molecules/atoms, the density of a gas is very low.
B. Gas molecules are in constant, random motion, so they take the shape and volume of whatever container they are in.
C. Since atoms are mostly empty space, gases can be compressed.
D. Gas molecules/atoms collide with each other and surfaces without losing energy. E. All of the above statements are consistent with KMT.

answer: option c.

explanation:

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
