Question

A 150 ml ice cube is taken from a 0°C freezer and left on the counter.

How much energy does it take from its surrounding environment in order to turn into liquid? (1 ml = 1 g) The latent of fusion is 335,000 J/kg.

Answer 1

50250 J

Step-by-step explanation:

From the question given above, the following data were obtained:

Volume of ice = 150 mL

Latent heat (L) = 335000 J/kg

Heat (Q) absorbed =?

Next, we shall convert 150 mL to g. This can be obtained as follow:

1 mL = 1 g

Therefore,

150 mL = 150 g

Next, we shall convert 150 g to Kg. This can be obtained as follow:

1000 g = 1 Kg

Therefore,

150 g = 150 g × 1 Kg / 1000 g

150 g = 0.15 Kg

Finally, we shall determine the heat absorbed. This can be obtained as follow:

Mass of ice (m) = 0.15 Kg

Latent heat (L) = 335000 J/kg

Heat (Q) absorbed =?

Q = mL

Q = 0.15 × 335000

Q = 50250 J

Thus, 50250 J was absorbed from the surrounding environment.
