1.	The densities of two substances are in the ratio 2: 3 and their specific heats are 0.12 and 0.09 CGS units respectively. The ratio of their thermal capacities per unit volume is
Answer» `8: 9` `1: 2` `3: 2` `4: 9` SOLUTION :`("THERMAL capacity (S)")/("Volume(V)") = s (m)/(v) = s rho` `:. (S_(1)//V_(1))/(S_(2)//V_(2)) = (s_(1) rho_(1))/(s_(2) rho_(2)) = (0.12)/(0.09) XX (2)/(3) = (8)/(9)`
