The graphical representation of the pressure law is always a straight line passing through the origin, only if the temperature scale is
A
Rankine
B
Celsius
C
Fahrenheit
D
thermodynamic
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Answer: D. thermodynamic (Pressure law P ∝ T requires an absolute scale like Kelvin (thermodynamic) for a line through the origin at T= 0, P= 0. Rankine is also absolute but less common in this context.)
