Click here for the Detailed Syllabus of IIT JEE Physics. Each species will experience the equal temperature change. From the above observation we conclude that, the temperature of the water before insertion of the thermometer was 45.5 ° C. A mixture of 1.78 kg of water and 262 g of ice at 0°C is, in  a reversible process, brought to a final equilibrium state where the water / ice ratio, by mass 1:1 at  0°C. Thus the mass of the water that changed into ice m will be the difference of mass of water mw  and mass of final state ms. To obtain mass of water that changed into ice m, substitute 1.78 kg for mass of water mw and 1.02 kg for mass of final state ms in the equation m = mw - ms. Jitender Singh and Shraddhesh Chaturvedi have used these questions to come up A thermometer of mass 0.055 kg and heat capacity 46.1 J/K reads 15.0°C. If the thermometer reads 44.4°C, what was the temperature of the water berfore insertion of the thermometer, neglecting other heat losses? Many candidates are facing problems in collecting Maths, Physics and Chemistry Topic wise notes collection for JEE… (c) In accordance to second law of thermodynamics, entropy change ΔS is always      zero.
