Charles Law Calculations

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

• 250 mL
• 204 mL
• 196 mL
• 160 mL

The volume of a sample of a gas at 273 ^oC is 200 liters. If the volume is decreased to 100 liters at constant pressure, what will be the new temperature of the gas?

• 0 K
• 546 K
• 273 K
• 100 K

A sample of oxygen gas in a closed system has a volume of 200 milliliters at 600 K. If the pressure is held constant and the temperature is lowered to 300 K, the new volume of the gas will be -

• 400 milliliters.
• 300 milliliters.
• 100 milliliters.
• 200 milliliters.

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

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

What type of relationship is Charles' Law?

• Inverse
• Direct
• Not enough information
• #goals

What is the formula Charles' Law?

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

If a balloon is cooled what will happen to the volume?

• Volume will increase
• Volume will decrease
• Volume will not change

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 are more travellers during summer vacation
• high temperature during summer season causes the air inside the tire to expand
• vehicles' tires are no well maintained
• there is too much air inside the tires

The graph for the Charles' law is

• True

• False

Julian and Jimmy are playing basketball outside in 82°C weather. If they leave the ball outside and temperature drops down to 53°C, what will happen to the volume of the gas in the ball if the pressure remains constant?

• volume will remain the same
• volume will increase
• volume will decrease
• volume will double in size
