Question 35

Gas Laws

Increasing the pressure of a gas

  1. A.lowers the average kinetic energy of the molecules
  2. B.decreases the density of the gas
  3. C.decreases the temperature of the gas
  4. D.increases the density of the gas
  5. E.increases the volume of the gas
Show the answer and explanation

Answer: D (increases the density of the gas)

Explanation

Higher pressure squeezes the same mass of gas into a smaller volume, so its density increases.
