Which of the following explains why the pressure of a gas increases when the volume of its container decreases, assuming that the temperature is held
constant?
A. The viscosity of the gas increases, which increases the frictional
force exerted on the sides of the container.
B. The number of collisions with the container's walls increases as
the gas has less room in which to move.
C. The density of the gas increases, which increases the
intermolecular forces between the gas and the sides of the
container.
D. The speed of the of the gas particles increases, which increses
the force of the collisions with the sides of the container.

Thomas his older brothers, who own a junk yard, on the weekends to earn extra money. he likes to them push broken-down cars to the back of the junk yard because it makes him feel strong. last saturday, they pushed three cars with different weights, and he noticed he used different amounts of force for each one. the cars were the following weights: white car: 2,700 kg red car: 1,500 kg blue car: 2,100 kg think about how much force is needed to move each car. which correctly lists the cars in order from the most to least amount of force needed to move them? a) white, blue, red b) blue, red, white c) red, white, blue d) white, red, blue
