Answer:
Kinetic theory explains why the volume of a container must expand when the temperature of the gas inside increases in order for the pressure to remain constant.
Step-by-step explanation:
Charles' law: for a fixed mass of gas at constant pressure the volume is directly proportional to the temperature.
Analysis of a gas when its temperature increases according to kinetic theory:
The temperature has increased therefore the molecules have more kinetic energy, so they move with a greater velocity.¹
If the container's dimensions do not change the molecules will travel across the container between the walls in less time (because they are moving faster and covering the same distance between the container walls). This will increase the rate of collisions, which would increase the pressure.²
But if the dimensions of the container increased then the molecules would cover a larger distance faster thereby maintaining a constant rate of collisions. This would maintain a constant pressure.

Let 
, a reflection over the x-axis consists in the following operation:
If we know that 
and 
, then the points translated over the x-axis are 
and 
, respectively. The most precise description of the shape is a rectangle for the following facts:
1) 
and 
.
2) 
and 
have the same x-component.
3) 
and 
have the same x-component.
4) and have the same y-component.
5) and have the same y-component.
A representation of the shape is included below as attachment.
Answer: 5.5 quarts = 22 cups
Step-by-step explanation:
1 cup = 4 cups
to convert cups to quart, just multiply by 4
5.5 x 4 = 22
