You have a block of ice at a temperature of -100°C. This block of ice is made from 180g H2O. The block of ice will be heated continually until it becomes super-heated steam at a temperature of 200°C Cice = 2.03 J/g-K ΔHfus=6.01 kJ/mol Cwater = 4.18 J/g-K Csteam = 1.84 J/g-K ΔHvap=40.67 kJ/mol What is the enthalpy change raising the temperature of 180 g of ice at −100 °C to 0°C? What is the enthalpy change upon melting 180...
An 12 g ice cube at -19?C is put into a
Thermos flask containing 100 cm3 of water at 20?C. By how much has
the entropy of the cube-water system changed when a final
equilibrium state is reached? The specific heat of ice is 2200 J/kg
K and that of liquid water is 4187 J/kg K. The heat of fusion of
water is 333 × 103 J/kg.

How much heat is required to change a 43.5 g ice cube from ice at -13.9°C to water at 32°C? How much heat is required to change a 43.5 g ice cube from ice at -13.9°C to steam at 118°C?
An ice cube at 0°C was dropped into 30.0 g of water in a cup at 45°C. At the instant all of the ice is melted, the temperature of the water in the cup was 19°C. How many moles of ice was the ice cube? What was the mass of the ice cube? ANSWER, moles: mol ANSWER, grams: 1 g Check
Calculate how many grams of ice at 0°C would be melted by 100 g of 100°C steam. Hint: heat will be transferred from the steam to the ice in two processes: •the steam will condense into liquid, and •that liquid will transfer heat until it is at the freezing point of water. Note that for water: Lf = 80 cal/g (ice), and Lv = 540 cal/g (steam) (Use calories) C(water) =1 cal/g*C Answer in grams no decimal places.
A) A 41 g ice cube at −21◦C is dropped into a container of water at 0◦ C. How much water freezes onto the ice? The specific heat of ice is 0.5 cal/g ·◦ C and its heat of fusion of is 80 cal/g. Answer in units of g. B) A 0.0602 kg ingot of metal is heated to 205◦C and then is dropped into a beaker containing 0.411 kg of water initially at 18◦C. If the final equilibrium state...
