the value of specific heat capacity of water is 4.2kj/kg.K
Specific heat of ice = 2.1kj/kg.k
Latent heat of fusion of ice = 0.336MJ/kg
Molar latent heat of fusion of ice= 1434.6j/mole
how do I do the calculations? please be very detailed, thank you? Molar Heat of Fusion of Ice-Sample Worksheet Data:...
We did the lab of latent heat of fusion of ice, and I am confused that what the 'water equivalent' represents. I thought it is the amount (kg) of water, but it is mccc according to this lab manual, which unit is (J/oC). Please answer what the water equivalent represents and the unit of it. - In this experiment, an ice cube of mass mt, assumed to be at 0°C, is placed in a calorimeter containing a mass of water...
Determination Of The Molar Heat of Fusion Of Ice Purpose The purpose of this result with its reported value that is s 6.01 kJ/mol. The molar heat of fusion (AH) of ice is the amount of heat required to melt 1 mole of ice experiment is to determine the molar heat of fusion of ice and compare the experimental Definition Heat of fusion of ice is the amount of heat required to melt ice. The more the ice to melt,...

I would really appreciate your help. God bless you Question 4 The molar enthalpy of fusion of ice at 0 °C and 1 atm pressure is 6024 J mol. The molar heat capacities at constant pressure of ice and water are 37.65 J Kmol and 75.30 J Kmol respectively, and may be taken as constant over the temperature range 0 to -20°C. Consider 2 mole of liquid water supercooled to -20 °C, which is allowed to freeze isothermally from liquid...
