When 204 g of a substance is heated to C and then plunged into a 97 g aluminum calorimeter cup containing?
En 204 g of a substance is heated to C and then plunged into a 97 g aluminum calorimeter cup containing 174 g of water at 12. C, the final temperature, as registered by a 19 g glass thermometer, is 34. C. What is the specific heat of the substance?
Answer: The heat out of the substance = heat into the cup + water + glass where q = m*c*t so 204*c*(332 - 34. 8) = 97*0. 91*(34. 8 - 12. 3) + 174*4. 2*(34. 8 - 12. 3) + 19*0. 84*(34. 8-12. 3) or 60629*c = 18788 so c = 18788/60629 = 0. 310 j/g-oc
