Charle's Law Theory

What is the formula Charles' Law?

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

Volume and temperature have a ______ proportionality.

• direct
• inverse
• linear
• exponential

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

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.

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

Which two variables must be held constant for Charles's Law to apply?

• pressure & volume

• volume & temperature

• pressure & amount of gas

• volume & amount of gas

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

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

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

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

What temperature scale must all temperature measurements be converted to?

• Celsius
• Fahrenheit
• Kelvin
• Does not matter

When the temperature of a gas decreases (with pressure and amount held constant), does the volume increase or decrease?

• Unaltered

• Remains constant

• Increase

• Decrease
