At constant pressure, the graph between V and T is:
Correct answer: C. Straight line
- A. Parabola
- B. Hyperbola
- C. Straight line
- D. Circle
Explanation
At constant pressure (isobaric process), the graph between volume (V) and temperature (T) is typically a straight line. This relationship is described by Charles's law, which states that the volume of a gas is directly proportional to its absolute temperature at constant pressure.

About Charles's Law
At constant pressure, the volume of a fixed mass of gas is directly proportional to its absolute temperature. Questions involve the Kelvin scale, the equation V₁/T₁ = V₂/T₂, volume-temperature graphs, and the need to distinguish Charles's law from Boyle's law, which relates pressure and volume.
