Two litre of an ideal gas at 42^ C is heated at a constant pressure to 357^ C . Then the final volume is

Options

  1. A6 L
  2. B2 L
  3. C4 L
  4. D3.5 L

Correct answer

C. 4 L

Step-by-step solution

Given, initial volume V₁ = 2 L Initial temperature T₁ = 42^ C = 42 + 273 = 315 K Final temperature T₂ = 357^ C = 357 + 273 = 630 K At constant pressure, using Charles's law: V₁ T₁ = V₂ T₂ 2 315 = V₂ 630 V₂ = 2 630 315 = 4 L Answer: 4 L
