A 0.20 Kg aluminum block at `80^oC` is dropped in a copper calorimeter of mass 0.05 Kg containing `200 cm^3` of ethyl alcohol at `20^oC`. What is the final temperature of the mixture? Given Density of ethyl alcohol = `0.81 g | cm^3` ; specific heat of ethyl alcohol `= 0.6 cal | g | '^oC` ; specific heat of copper `= 0.094 cal | g | '^oC`, specific heat of `Al = 0.22 cal | g |
