Question

Calculate the heat required to convert 175 grams of ice (at the melting point) completely to steam (at the boiling point)

Answer 1

q1 = heat required to melt ice @ zero C to liquid H2O @ zero C.
q1 = mass ice x heat fusion of ice = ?
q2 = heat required to raise T of liquid H2O from zero C to 100 C.
q2 = mass H2O x specific heat H2O x (100-0) = ?
q3 = heat required to vaporize the liquid H2O @ 100 C to steam @ 100 C.
q3 = mass H2O x heat vaporization = ?
Total heat = q1 + q2 + q3 = ?
