200 gm of water and 7.5 gm of ice are in thermal equllibrium at atmospheric pressure in a copper calorimeter of mass 150 gm. If lead shots of mass 100 gm heated to 180^(@)C are dropped into the calorimeter. Find the resultant temperature and the quantity of ice left (neglect the heat lost due to radiation). Specific heat of copper = 0.1 "cal/gm"-^(@)C, specific heat of lead = 0.03 "cal/gm"-^(@)C

1.	200 gm of water and 7.5 gm of ice are in thermal equllibrium at atmospheric pressure in a copper calorimeter of mass 150 gm. If lead shots of mass 100 gm heated to 180^(@)C are dropped into the calorimeter. Find the resultant temperature and the quantity of ice left (neglect the heat lost due to radiation). Specific heat of copper = 0.1 "cal/gm"-^(@)C, specific heat of lead = 0.03 "cal/gm"-^(@)C
Answer» ANSWER :`0^(0)C,0.25 GM` of ICE is MELT
