<span>-4x -2<8
Add 2 to both sides
-4x<10
Divide -4 on both sides
Final Answer: x > -10/4 or -2 1/2 *Both answers are equivalent to each other.

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.
Answer:
Mild-Level 1: X=10
Medium-Level 2: X=21
Spicy Level 3: X=83
Step-by-step explanation:
You have to make sure each expression equals 90 degrees

Answer:</h2>
<u>The pressure will be 176 k Pa</u>
<h2>
Step-by-step explanation:</h2>
Boyle's law states that the product of volume and pressure gives us a constant value so we can write the expression as
P1V1 = P2V2
By arranging the equation we get
P1V1 / V2 = P2
Putting the values
(132 x 20 ) / 15 = P2
P2 = 176 k Pa
