Gay-Lussac's Law

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 temperature scale must all temperature measurements be converted to?

• Celsius
• Fahrenheit
• Kelvin
• Does not matter

Pressure and temperature have a(n) _________ proportionality.

• direct
• inverse
• linear
• exponential

Which two variables must be held constant for Gay-Lussac’s Law to apply?

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

At constant volume, what happens to temperature of a gas when the pressure doubles?

• The temperature also doubles.
• The temperature decreases to half its original volume.
• The temperature doesn't change.
• The temperature quadruples.

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
