Chapter 10: Gases (Answer Key) Name and briefly describe the following gas laws. Be sure to include a mathematical expression that represents each law. a. Boyle’s Law : Pressure and volume (inversely proportional), as pressure increases, volume decreases. P 1 V 1 = P 2 V 2. b.
In chemistry, the concentration of a solution is often measured as Molar Concentration or Molarity, abbreviated M. The Molarity of a solution is an indication of the number of moles of a solute in a certain
Answer Key. A mixture of 4.5% H2, 76% O2, and 19.5% N2 has a total pressure of 2.3 atm. What is the partial pressure of each of the gases? = (0.045)(2.3 atm) = 0.10 atm. = (0.76)(2.3 atm) = 1.75 atm. = (0.195)(2.3 atm) = 0.45 atm. Check your answer by adding the individual gases: 0.10 atm + 1.75 atm + 0.45 atm = 2.30 atm.
Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other.
Pressure is defined as the force applied divided by the area over which it is applied. A gas pressure results from the many collisions between gas particles and a surface.
Robert Boyle observed the relationship between the pressure and volume for a gas sample. These two variables are inversely proportional. This means that when the pressure goes up the volume goes down. This is expressed in the equation P1 × V1 = P2 × V2, which is known as Boyle’s Law. The
