Equal volumes of copper and mercury have the same thermal capacity. Sp. heat of mercury is 0.046" cal/gm/"^(@)C and density is 13.6 g/c.c. What is the density of copper if its specific heat is 0.090 ? |
|
Answer» `0.695 g//cc` or `V xx 13.6 xx0.046 =V xx d xx 0.09` `THEREFORE d =(13.6xx0.046)/(0.09)=6.95` g/c.c. `therefore` Correct CHOICE is (b). |
