Question
How much heat is required to vaporize 225 g of ice from -46.8 o C to steam at 173.0 o C?

q1 = heat to move ice from -46.8 C to zero C
q1 = mass ice x specific heat ice x (Tfinal-Tinitial) = ?
q2 = heat to melt ice @ zero C to water @ zero C.
q2 = mass ice x heat fusion water = ?
q3 = heat to move T of water from zero C to 100 C
q3 = mass water x specific heat H2O x (Tfinal-Tinitial) = ?
q4 = heat to vaporize H2O @ 100 C to steam @ 100 C
q4 = mass water x heat vaporization = ?
q5 = heat to move T of steam from 100 C to steam @ 173.0 C
q5 = mass steam x specific heat steam x (Tfinal-Tinitial) = ?
Total heat required = q1 + q2 + q3 + q4 + q5 = ?
