Question

Among the quantities, density $\left(\rho \right)$, temperature(T), enthalpy(H), heat capacity$\left(C_{\rho }\right)$, volume (V) and pressure (P), a set of intensive variables are $:$

• A. $(\rho ,T,H)$
• B. $(H,T,V)$
• C. $(V,T,C_{\rho })$
• D. $(\rho ,T,P)$

Answer 1

Answer: (D)

$(\rho ,T,P)$

Among the quantities, density ($\rho$), temperature(T), enthalpy(H), heat capacity($C_p$), volume (V) and pressure (P), a set of intensive variables are density ($\rho$), temperature(T) and pressure (P). Other intensive properties are surface tension, viscocity, refractive index, melting point, boiling point and specific heat. These properties are independent of the amount of matter.

Note:
Energy, volume and enthalpy are extensive properties whose values are dependent on the mass of the system.
