The mass,specific heat capacity and initial temperature of a sphere is 1000gm,1/2 cal/gm degree C and 80 degree C respectively. The mass of the liquid and the caloriemeter are 900 gm and 200 gm respectively,and initially both were at room temperature 20 degree C. Both caloriemeter and the sphere are made of same material. If the hot sphere is dropped in the caloriemeter, the steady state temperature after mixing is found to be 40 degree C, then the specific heat capacity of unknown liquid is 1) 0.25 cal/gm degree C 2) 0.5 cal/gm degree C 3) 1 cal/gm degree C 4) none of these Ans given is option 3. Please give detailed explanation. I won't be able to understand concise answers. |
