A soccer player twists her ankle on the field. The atheltic trainer applies an ice bag with 260 g of ice inside. How much heat, in joules, wil be absorbed, to melt all the ice to 0°C?

Q = 8.68 × 10⁴ J

Explanation:

We can calculate the heat required to melt a mass of ice, that is, to change it from the solid phase to the liquid phase, at a constant temperature of 0 °C, using the following expression.

Q = ΔH°f × m

where,

Q = ΔH°f × m

Q = 334 J/g × 260 g

Q = 8.68 × 10⁴ J

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
