Steam at 100 degree C is added to ice at 0 degree C. Find the amount of ice melt

Question

Steam at 100 degree C is added to ice at 0 degree C. Find the amount of ice melted and the final temperature when the mass of steam is 11 g and the mass of ice is 56 g.________ Your response differs from the correct answer by more than 10%. Double check your calculations, g_________ Your response differs from the correct answer by more than 10%. Double check your calculations. Degree C Repeat with steam of mass 3.2 g and ice of mass 56 g.___________ Your response differs from the correct answer by more than 10%. Double check your calculations, g_______________ degree C

Explanation / Answer

Heat of vapourization of water 2260j/g

specific heat of watr 4.186j/g.c

heat of fusion of water 335.55

steam supplies a total of 2260+100*4.186 = 2679j/g at 0c

a) 11 g steam supplies 29469 j

56g of ice requires = 20977 j to meet

therefore all ice is melted ( 29469 >20977) and excess energy heats water to ( 29469-20977)/4.186*(11+56)

= 30.27 C

b) 3.2g steam supplies 2675.5 j

56g of ice requires 56*355.55 = 15100 j to meet

only part of ice melted (2675.5 < 15100) and this is 2675.5/355.55 = 7.5g
