The graphical representation of the pressure law is always a straight line passing through the origin, only if the temperature scale is
Rankine
Celsius
Fahrenheit
thermodynamic
Explanation
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.)
