Questions
Two spheres of radii in the two ratios 2 : 3 have specific heat in the ratio 3 : 2. What is the ratio of their thermal capacities?
detailed solution
Correct option is D
Thermal capacity is m.s=43πR3.sdwhere d is the density of the body. Thermal capacity of first sphereThermal capacity of second sphere=4πR13/3s1d4πR23/3s2d =R1R23s1s2 =23332=4:9Talk to our academic expert!
