1. Pressure of a gas (decreases, increases) if the volume decreases when temperature is constant.
2. Pressure of a gas (decreases, increases) if the volume increases when temperature is constant.

3. The (left, right) cylinder shows that less volume results in increased pressure.
4. From left to right, the pressure on the cylinders (increases, decreases) because the weights are greater.
5. As the volume increases, there are (more, fewer) collisions between the particles.
6. A greater number of collisions results in (greater, less) pressure.

7. Boyle’s law only applies when the (temperature, pressure) is constant

Mo5-L4: Lesson Review Quiz (True or False)

Directions: On the line before each statement, write T if the statement is true or F if the statement is false. If the
statement is false, change the underlined word(s) to make it true. Write your changes on the lines provided.

1. The kinetic molecular theory explains how particles in matter behave.

2. The amount of force applied per unit of area is volume.

3. The pressure of a gas decreases if the volume decreases and temperature is kept constant.

4. As the temperature of a gas increases, its volume increases, if pressure is kept constant.
