प्रश्न
Two metals A and B have specific heat capacities in the ratio 2:3. If they are supplied same amount of heat then
If specific heat capacity of metal A is 0.26 Jg-1 0C-1 then calculate the specific heat capacity of metal B.
उत्तर
It is given that, ratio of specific heat capacities, `"C"_"A"/"C"_"B" = 2/3` and `"C"_"A" = 0.26`
Calculating we get, CB = 1.5 × 0.26 = 0.39.
Therefore, specific heat capacity of metal B is 0.39 Jg-1°C-1.
