9.3 Quizziz Charles Law

What is the formula for Boyle's Law?

• P₁V₁=P₂V₂
• P₁V₁/P₂V₂
• P₁V₂=P₂V₁
• P₁/V₁=P₂/V₂

There are 40 liters of helium in a balloon at 100 K. If the temperature of the balloon is increased to 200 K, what will the new volume of the balloon be?

• 80 L
• 45 L
• 54 L
• 45.33 L

Tom wants his balloon back to normal size so he decides to put it on a heating vent. If the balloon initially has a volume of 0.6 L and a temperature of 293 K, what will the volume of the balloon be when it heats up to a temperature of 176°C?

• 0.39 L
• 0.92 L
• 0.78 L
• 0.92 K

What is 50 C in Kelvin?

• 223
• 323
• 100
• 50

If 200 L of a gas at 27°C is cooled to -33°C at a constant pressure, the volume will be

• 250 L

• 204 L

• 196 L

• 160 L

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.

Which among the units of measurements below can be the standard unit of temperature?

• Celsius

• Centigrade

• Fahrenheit

• Kelvin

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.

At a constant temperature, pressure increases in Boyle's Law. What happens to the volume?

• increases

• decreases

• stays the same
