Determine the relationship of volume and temperature at
constant pressure of a gas through experiment/observation/
video clip/etc.

Describe the relationship between volume and temperature at
constant pressure from a given data/ graph/simulation / video
clips/etc.,

Cite and appreciate situations where Charles’ Law is observed.

Create video vlog to present the result of experiments.

Multiple Choice

At constant pressure, what happens to the volume of a gas when the absolute temperature doubles?

• It is halved.

• It is doubled.

• It is quadrupled.

• It remains the same.

Multiple Choice

According to Charles’ law, what
happened to the volume if the
temperature of gas is increased?

• The volume will increase.

• The volume will decrease.

• The pressure will increase.

• The pressure will decrease.

Multiple Choice

Which is evident in the graph?

• As temperature increases volume increases

• As temperature increases volume increases

• As temperature decreases volume decreases

Multiple Choice

Records show that the incident of tire
explosion is high during summer season.
Which of the following gives the best
explanation for this observation?

• There is too much air inside the tires.

• Vehicles’ tires are not well maintained.

• There are more travelers during summer vacation.

• High temperature during summer season causes the air inside the tire to expand.

Multiple Choice

A basketball was left in a cold garage during the cold weather. Based on Charles law, which is true about the molecules inside the ball when the temperature drops at constant pressure?

• Molecules will increase in volume.

• Molecules will slow down decreasing the volume.

• Molecules move randomly decreasing the volume.

• Molecules move randomly increasing the volume.
