Question

Draw the heating curve for ice at -30.0 °C to steam at 130.0 °C and label the phases on the lines in the heating curve. Calculate the enthalpy (in kJ) for converting 50.0 g of ice at -15.0 °C to water at 57 °C. The specific heat of ice = 2.09 J/g-°C. The specific heat of water = 4.184 J/g-°C. The specific heat of steam = 1.84 J/g-°C. H_fus for water = 6.01 kJ/mol. H_vap for water = 40.67 kJ/mol. Give 3 sig figs in your answer.

Step 1

Heating ice from -15.0 °C to 0 °C q1 = (mass) x (specific heat of ice) x (change in temperature) q1 = (50.0 g) x (2.09 J/g-°C) x (15.0 °C) = 1570 J Show more…
