Gay-Lussac's Law Problems #1 - 10. Problem #1: A 30.0 L sample of nitrogen inside a rigid, metal container at 20.0 °C is placed inside an oven whose temperature is 50.0 °C. The pressure inside the container at 20.0 °C was at 3.00 atm.
1 kwi 2021 · Gay-Lussac’s law or Amonton’s law states that the absolute temperature and pressure of an ideal gas are directly proportional, under conditions of constant mass and volume. In other words, heating a gas in a sealed container causes its pressure to increase, while cooling a gas lowers its pressure.
A common student error is to use Dalton's Law, but then use the total pressure value in the combined gas law instead of using the correct value. The correct pressure to use for P 1 is the 699.8 value, not the 725 value.
Problem #2: A sample of argon gas at STP occupies 56.2 liters. Determine the number of moles of argon and the mass of argon in the sample. Solution: 1) Rearrange PV = nRT to this: n = PV / RT. 2) Substitute: n = [(1.00 atm) (56.2 L) ] / [ (0.08206 L atm mol¯ 1 K¯ 1) (273.0 K)] n = 2.50866 mol (I'll keep a few guard digits)
Amonton's Law Toward the end of the 1600s, the French physicist Guillaume Amontons built a thermometer based on the fact that the pressure of a gas is directly proportional to its temperature. The relationship between the pressure and the temperature of a gas is therefore known as Amontons' law .
Amonton's law, also known as the Gay-Lussac law, describes the relationship between pressure and temperature. As the pressure of a gas increases, temperature increases proportionally if volume is held constant. In this worksheet, students will solve a series of word problems using the equation derived from this law.
Learn what Gay Lussac's law is, real-life examples of Gay-Luccas's law, and see several solved example problems of this gas law.
