How much heat is added to a 10.0 g of ice at -20.0 degrees Celsius to convert it to steam at 120.0 degrees Celsius?
compute and add the following heats:
heat to heat ice from -20C to 0C
heat to melt ice at 0C
Heat to heat water from 0 to 100C
heat to convert water to steam at 100C
heat to heat steam from 100 to 120C
