An ice-cube tray is filled with 69.6 g of water. After the filled tray reaches an equilibrium temperature 20.0 degree C, it Is placed in a freezer set at -8.00 degree C to make ice cubes. Describe the processes that occur as energy is being removed from the water to make ice. Calculate the energy that must be removed from the water to make Ice cubes at -8.00 degree C. KJ

Suppose you put some water in your ice-cube tray and then place the tray in the freezer. Consider a single ice cube that starts out as 31.0 ml of liquid water at 20.0°C. To determine the energy that must be removed from the water to convert it to an ice cube, we must consider the process in three stages. For stage 1, determine how much energy must be removed from the water to cool it to water at 0.00°C Enter...

4-10. The latent heat of fusion of ice is 333 kJ/kg. In the freezer compartment of a refrigerator, a tray holds 12 cubes of water each of mass 8.0 g. If the C.O.P. of the refrigerator is 3.3. how many kilowatt-hours of electrical energy would be required to run the refrigerator to change the water cubes (at 0°C) into ice cubes (at 0°C)?

m Rev A Carnot freezer that runs on electricity removes heat from the freezer compartment, which is at -10°C and expels it into the room at 25°C. You put an ice-cube tray containing 425 g of water at 12 C into the freezer. Part A What is the coefficient of performance of this freezer? AZOO ? K = Submit Request Answer Part B How much energy is needed to freeze this water? Assume at the end of the process all...

An ice cube with a mass of 0.12 kg is at 0 degrees Celsius. The ice cube is dropped into a styrofoam cup that holds 0.6 kg of water at 25 degrees Celsius. Assuming that the cup and the surroundings can be ignored, how much ice remains once the water and ice are in thermal equilibrium? a) 0 g b) 28.5 g c) 247.3 g d) 187.9 g e) 112.0 g

A cube of ice is taken from the freezer at -5.5 degree C and placed in a 85-g aluminum calorimeter filled with 330 g of water at room temperature of 20.0 degree C. The final situation is observed to be all water at 16.0 degree C. The specific heat of ice is 2100 J/kg C degree, the specific heat of aluminum is 900 J/kg C degree, the specific heat of water is is 4186 J/kg. C degree, the heat of...

A 50g ice cube is taken out of a freezer at 0 degrees Celsius and put in a thermally isolated container containing 200g of water at the temperature 60 degrees Celsius. Find the temperature of the system at equilibrium. ANSWER: 32 degrees Celsius I don't understand why you have to involve (moles of ice x delta H of fusion) to the equation? Please help! Thanks!
