A gas occupies 2.0 L at 300 K and 1 atm. If the pressure is kept constant and the temperature is increased to 600 K, what is the new volume?

  1. 1.0 L
  2. 2.0 L
  3. 4.0 L
  4. 6.0 L
Show the answer and explanation

Correct answer

C. 4.0 L

Principle or equation

Charles's law (constant pressure): V1/T1 = V2/T2.

Why this answer is correct

V2 = V1 × (T2/T1) = 2.0 L × (600/300) = 4.0 L.

Example

If a gas at 300 K occupies 1 L, at 900 K it occupies 3 L.
