Question 1

A .20-kg ice cube at 0.0°C has sufficient heat added to it to cause total melting, and the resulting water is heated to How much heat is added? For water LF = 334,000 J/kg, LV = 2.256 × 106 J/kg, the c = 4.186 x 103 J/kg ∙ C.
◦ 81 kJ
◦ 14,000 kJ
◦ 59 kJ
◦ 130 kJ

Question 2

How much heat must be added to a 8.0-kg block of ice at -8°C to change it to water at  The specific heat of ice is 2050 J/kg ∙ °C, the specific heat of water is 4186 J/kg ∙ °C, the latent heat of fusion of ice is 334,000 J/kg, and 1 cal = 4.186 J.
◦ 140 kcal
◦ 810 kcal
