Gay Lussac and 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

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

How is pressure measured?

• kPa, mmHg, L
• kPa, mmHg, s
• kPa, mmHg, torr
• kPa, mmHg, torr, atm 

What is the formula Charles' Law?

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

The relationship of which two variables are compared in Gay-Lussac’s Law?

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

What is the formula for Gay-Lussac’s Law?

• P₁/T₁ = P₂/T₂
• P₁/V₁ = P₂/V₂
• T₁/P₁ = T₂/P₂
•  P₁•T₁ = P₂ • T₂

The oxygen tanks on the sideline can be very dangerous if heated. Suppose an oxygen tank has a pressure of 120 atm at a room temperature of 25°C. If the temperature on the turf or field increases to 51°C, what will the resulting pressure of the oxygen tank be if the volume and amount of gas does not change?

• 130 atm
• 804 atm
• 1.30 atm
• 254 atm

Waiting to play the Broncos, the Patriots notice the change in the barometric pressure that occurs when arriving in Denver, CO. In Boston, if the temperature is 25°C at a barometric pressure of 101.3 kPa, what would the temperature of the air be if the barometric pressure decreased to that of Denver’s; 84.0 kPa?

• 175 K
• 247 K
• 247 L
• 28.5 K

A gas has a pressure of 1.50 atm at a temperature of 273 K.  What will be the pressure at 410 K?
