Charles's Law

A sample of neon gas at 760 torr has a volume of 10.0 L and a temperature at 35℃. Solve for the new volume of the gas after the temperature has been changed to 80℃ provided that the pressure is held constant.

(a)  

2. A cylinder with a movable piston contains 550 mL air at 15 K. If the pressure is held constant, at what temperature would you expect the volume to be 250 mL?

(a)  

3.      A gas occupies 900.0 mL at a temperature of 27.0 °C. What is the volume at 32.0 °C?

(a)  

According to Charles’s law, the relationship between the temperature and the volume of a gas is

• direct

• inverse

• exponential

• inverse square

Using Charles's Law, if the initial temperature of a gas is 300K and its volume is 50 liters, what would be the volume if the temperature is increased to 600K (assuming pressure remains constant)?

• 25 liters

• 50 liters

• 100 liters

• 150 liters

In an experiment verifying Charles's Law, if a plot of gas volume versus temperature (in Kelvin) is not a straight line, what could be a possible reason?

• The pressure was not kept constant.

• The gas did not follow Charles's Law.

• The temperature was measured in Celsius instead of Kelvin.

• All of the above could be reasons.

What is the formula Charles' Law?

• V = T

• VT = VT

• T₁ / V_{1 =} T₂ / V₂

• V₁ / T₁ = V₂ / T₂

• Final volume and final temperature

• Initial volume and final temperature

• Initial volume and initial temperature

• Final volume and initial temperature

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

• pressure & volume

• volume & temperature

• temperature & pressure

• volume & moles (amount of gas)

What remains constant according to Charles’ Law?

• Length

• Pressure

• Temperature

• Volume
