What is the formula Charles' Law?

• V = T
• VT = VT
• T₁ / V_{1 =} T₂ / V₂
• V₁ / T₁ = V₂ / T₂

(Charles Law) There are 65 liters of helium in a balloon at 35 K. If the temperature of the balloon is increased to 40 K, what will the new volume of the balloon be?

• 40 L

• 70 L

• 74.3 L

• 75.9 L

(Charles Law) 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

In Charles' Law the pressure remains constant.

• True
• False

If 200 L of a gas at 57°C is cooled to 33°C at a constant pressure, the volume will be

• 250 L

• 9.4 L

• 115 L

• 345 L

In order to solve gas law calculations, temperature must be measured in:

• Fahrenheit
• Celsius
• Kelvin
• It doesn't matter 

What type of relationship exists between the temperature and volume of a gas?

• inverse relationship

• direct relationship

• reverse relationship

• none of the above

_________ is a measure of the amount of space that matter takes up.

• Mass

• Matter

• Volume

• Pressure

With the help of his dad, a boy inflated a bunch of balloons outside on a hot, sunny day. The outdoor temperature was 26 degrees Celsius. Then the boy took the balloons inside his air-conditioned house, where the temperature was 20 degrees Celsius. What do you think happened to the balloons after they had been inside the cool house for a while?

• The balloons shrank

• The balloons got bigger

• Nothing happens to the balloons

• The balloons exploded
