Question

Ice actually has negative caloric content. How much energy, in each of the following units, does your body lose from eating (and therefore melting) 71 g of ice? Heat of fusion for water is 6.02 kJ/mol.

Answer 1

The heat loss Q = 1.6 KJ

Step-by-step explanation:

Mass of the ice = 71 gm

Heat of fusion for water is ΔH = 6.02
`(KJ)/(mol)`

No. of moles of ice

`n = (m)/(M)`

`n = (71)/(267)`

n = 0.266

Now Heat loss is

Q = ΔH × n

Q = 0.266 × 6.02

Q = 1.6 KJ

Therefore the heat loss Q = 1.6 KJ
