Question

Among the following, the intensive properties are
(i) molar conductivity
(ii) electromotive force
(iii) resistance
(iv) heat capacity

A. (i) and (ii)  
B. (i), (ii) and (iii)
C. (i) and (iv)
D. (i) only
Answer :   (i) and (ii)
Solution :
Mass independent properties ( molar conductivity and electromotive force ) are intensive properties. Resistance and heat capacity are mass dependent, hence extensive properties.
