Question

What is the shape of the graph for the pressure-temperature for an ideal gas?

  1. Hyperbola
  2. Parabola
  3. Straight line
  4. Semi-circle

The correct answer is: Straight line


    According to Ideal gas Equation,
    PV = nRT
    At constant volume, P ∝ T.
    Hence, the graph between P and T is a straight line.
