basic concept of calorimetry and heat transportation

@ anjali 
kindly elaborate your ques a little bit , so, that we can help u in a better way . 
acc to the principle of calorimetry 
if there is a diffrence between the temp. of two objects and they are brought near each other the heat lost by the hotter body will be equal to the heat gained by the colder body . , provided there is no heat lost in the surrounding . 
HEAT LOST = HEAT GAINED 
HOPE IT CLEARS 
ALL THE BEST ..
