Answer 1

Answers Mass of Kettle (Iron) - 1.93 kg = 1930 g = mi Specific heat capacity of Ison = 0.444 7/gc = cp Mass of water = 2.73 kg = 2730 g Heat capacity of water a 40184 J/gcc. Initial temperature a 27.5°c het final temperature - T AT = (T-27.5%) Then Heat gained by Kettle = mc, (AT) 1930 x0.444 510% (T-27.5)% - 856-92 (T-27.5) Similarly heat gained by 2-13 kg water = 2780g x 4.1849/gc (AT). = 11422.32 (T-27.5°C) Heat released by not water a meat If T = 13.9°C Then heat gained by Kettle = 858.92 (73-7-27:5) = 39589.73 ~ 3.96 X 104 Heat gained by water = 11422.32 (737-275) I 2 527711. J - 15.28 X 10531
