Question

A 100.0 g sample of ice at -15°C is heated until it is converted to water vapour at 120.0°C.
Calculate the total energy change.

DrBob222 · Answer

You do this in steps.
q1 = heat to raise T of solid ice at -15 C to zero C.

q2 = heat to melt ice

q3 = heat to raise T of liquid H2O from zero C to 100 C

q4 = heat to vaporize liquid H2O at 100 C to steam at 100 c.

q5 = heat to raise T of steam from 100 c to 120 C.

Total is sum of each step.

Do what you know to do and post your work if you have question. Explain what trouble your are having.
