H and E are extensive/intensive properties.

Out of internal energy (I), boiling point (II), pH (III) and E.M.F. of the cell (IV) intensive properties are :

True or false: Both E_(cell)^@ and DeltaG^@ for the cell reaction are intensive properties.

What are intensive properties ? Give examples.

Two cells, of e.m.f. 2E and E, and internal resistance 2 r and r respectivley are connected in parallel. Obtain the expression for the equivalent e.m.f and the internal resistance of the combination?

Derive a relation b/w e.m.f E,potential V , internal resistace 'r' of a cell and external resistance 'R' prove that e.m.f . Is more than potential difference .

Define e.m.f. Does it represent force?

A cell of e.m.f. 4 V and of negligible internal resistance is connected in series with a potentiometer wire of length 400 cm. The e.m.f. of a Leelanche cell is found to be balacned at 150 cm from the positive end of the potentiometer wire. What is the e.m.f. of the Leclanche cell ?

A number of identical cells, n , each of e.m.f. E, internal resistance r connected in series are charged by a d.c. source of e.m.f. E', using a resitor R Deduce the expresison for the charging current and the potential difference across the combination of the cells.

Define virtual e.m.f. and find the relation between virtual e.m.f. and maximum e.m.f. n a.c.
