How much heat is necessary to change 560g of ice at -9 degrees Celsius to water at 20 degrees Celsius?

Explain why ice melts at 0 degrees C without an increase of temperature, even though heat flows from the surroundings to the system? ... When a solid reaches its melting point, additional heat must be absorbed to convert it to a liquid. Therefore, fusion of a solid is endothermic.

Explanation:

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
