Q. Given are statements for certain thermodynamic variables, (A) Internal energy, volume (V) and mass (M) are extensive variables. (B) Pressure (P), temperature (T) and density ($\rho$) are intensive variables. (C) Volume (V), temperature (T) and density ($\rho$) are intensive variables. (D) Mass (M), temperature (T) and internal energy are extensive variables. Choose the correct answer from the options given below :
A) (B) and (C) Only
B) (C) and (D) Only
C) (D) and (A) Only
D) (A) and (B) Only
Explanation
[Solution by Dr. Abubacker] Internal energy, volume and mass depend on the amount of matter (extensive); pressure, temperature and density do not (intensive). So (A) and (B) are true, while (C) (volume is extensive) and (D) (temperature is intensive) are false. Answer (4).
