Problem

Three liquids A, B and C having same specific heats have masses m,

2m

and

3m

. Their temperatures are,

\theta

2\theta

and

3\theta

respectively. For temperature of mixture, match the following two columns.

Column I	Column II
(a) When <i>A</i> and <i>B</i> are mixed	(p) $\frac{5}{2}\theta$
(b) When <i>A</i> and <i>C</i> are mixed	(q) $\frac{5}{3}\theta$
(c) When <i>B</i> and <i>C</i> are mixed	(r) $\frac{7}{3}\theta$
(d) When <i>A</i> , <i>B</i> and <i>C</i> all are mixed	(s) $\frac{13}{5}\theta$
