Question

Fifty grams of ice at 0◦ C is placed in a thermos bottle containing one hundred grams of water

at 6◦ C. How many grams of ice will melt? The heat of fusion of water is 333 kJ/kg and the
specific heat is 4190 J/kg · K.Immersive Reader

Answer 1

7.55 g

Step-by-step explanation:

Heat of fusion = 333kj/kg

Heat capacity, c = 4190 j/kg /k

Heat capacity in j/g /k = 0.4190

Let the Number of grams of ice that will melt = n

Number of grams * heat of fusion = heat capacity * temperature change

n * 0.333 = 0.419 * (6-0)

0.333n = 2.514

n = 2.514 / 0.333

n = 7.5495

n = 7.55 gram

Hence, the number of gram of ice that will melt is 7.55 grams
