1.04 Charles Law Additional Practice

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

10 L of a gas is collected at 100 K and allowed to expand to 30.0 L. What is the new temperature?

• 400 K
• 300 K
• 275 K
• 250 K

Volume and temperature have a ______ proportionality.

• direct
• inverse
• linear
• exponential

What temperature scale must all temperature measurements be converted to?

• Celsius
• Fahrenheit
• Kelvin
• Does not matter

The relationship of which two variables are compared in Charles’s Law?

• pressure & volume
• volume & temperature
• temperature & pressure
• volume & moles (amount of gas)

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

• The temperature also doubles.
• The temperature decreases to half of its original volume.
• The temperature doesn't change.
• The temperature quadruples.
