For a fixed-volume sample of gas, the linear P vs T plot demonstrates:
- A
P and T are inversely related
- Bcheck_circle
Pressure is directly proportional to absolute temperature
- C
Pressure is independent of T
- D
Volume is inversely proportional to T
Explanation
At constant V and n, ideal gas behavior gives P/T = constant (Gay-Lussac's law); a straight line through origin confirms direct proportionality.
