Charles' Law

As the temperature increases, the molecules within any given gas begin to move around more quickly. What will happen to a helium balloon on a cold day?

• The balloon will explode.

• The balloon will crumble.

• The balloon will be flattened.

• The balloon will remain inflated.

Which of the following statements is TRUE in describing the relationship between volume and temperature at constant pressure?

• The Kelvin temperature and the volume of a gas are directly related at constant pressure.

• The pressure of a fixed amount of a gas is directly proportional to the absolute temperature (Kelvin).

• The volume of a given mass of gas held at constant temperature is inversely proportional to its pressure.

• The volume of a gas varies directly with the number of moles and absolute temperature and inversely proportional with pressure.

Charles’ Law experiment showed that various gases expanded by the same amount when heated through the same temperature interval. What is the mathematical expression of Charles’ Law?

• V1T1 = V2T2

• V1/T2 = T1/V2

Jacques Alexandre Charles performed an experiment in a balloon, hot water, and cold water. Which of the following statements is proposed in Charles’ Law?

• The Kelvin temperature and the volume of a gas are directly related at constant pressure.

• The pressure of a fixed amount of a gas is directly proportional to the absolute temperature (Kelvin).

• The volume of a given mass of gas held at constant temperature is inversely proportional to its pressure.

• The volume of a gas varies directly with the number of moles and absolute temperature and inversely proportional with pressure.

A 132 mL of gas is measured at 380C. If the pressure remains constant, what will be the volume of the gas at 100C?

• 34.74 mL

• 120. 12 mL

• 311.15 mL

• 37, 375.8 mL

Application of Charles’ Law can be seen as one flies in a hot air balloon, when heated, causes the air to expand; thus, becomes lighter and so it rises. Which of the following is another application of Charles’ Law?

• A flat tire takes up less volume than an inflated tire.

• An inflated balloon shrinks when placed inside the refrigerator.

• A helium-filled balloon weights much less than an identical balloon filled with air.

• A syringe plunger being pressed down to draw out the fluid causes the volume inside the syringe to decrease while increasing pressure inside.
