Understanding Gay-Lussac's Law

What does Gay-Lussac's Law relate in a gas sample?

• Number of particles and volume

• Volume and temperature

• Pressure and temperature

• Pressure and volume

Why must temperature be measured in Kelvin when using Gay-Lussac's Law?

• Kelvin is easier to calculate

• Kelvin avoids negative values

• Kelvin is a larger unit

• Kelvin is the standard unit for pressure

In the equation P1/T1 = P2/T2, what do the subscripts 1 and 2 represent?

• Different pressures only

• Different gases

• Different states of the same gas

• Different volumes

If a gas at 285 K exerts a pressure of 1.25 atm, what is the new pressure when cooled to 271 K?

• 1.50 atm

• 1.00 atm

• 1.30 atm

• 1.19 atm

What must be consistent on both sides of the Gay-Lussac's Law equation?

• The type of gas

• The units of measurement

• The number of particles

• The color of the container
