Understanding the Combined Gas Law

Which three gas laws are combined to form the Combined Gas Law?

• Boyle's Law, Avogadro's Law, and Gay-Lussac's Law

• Avogadro's Law, Charles's Law, and Gay-Lussac's Law

• Boyle's Law, Charles's Law, and Gay-Lussac's Law

• Boyle's Law, Avogadro's Law, and Charles's Law

What must be consistent when using the Combined Gas Law formula?

• All units, including pressure, volume, and temperature

• Only the units of pressure and temperature

• Temperature units only

• Pressure and volume units only

In the first example, what is the new pressure of the gas when the temperature increases to 400 K and the volume decreases to 20 liters?

• 5 atmospheres

• 3 atmospheres

• 2 atmospheres

• 4 atmospheres

In the second example, what is the original volume of the gas if the final volume is 125 milliliters?

• 200 milliliters

• 215 milliliters

• 230 milliliters

• 250 milliliters

What is the new temperature of the gas in the third example when its volume decreases to 20 liters and its pressure triples?

• 348 K

• 358 K

• 368 K

• 378 K
