Ice Cream Analysis
Peng, Klouda
The purpose of this lab was to produce ice cream after calculating a specific
amount of liquid nitrogen needed to cool the ice cream mixture. To calculate the amount
of liquid nitrogen, the theory of the Conservation of Energy was used. The conservation
of Energy states Energy

= Δ Energy. This is used both for the
ice cream mixture and the liquid nitrogen. For the ice cream mixture, there is no energy
going into the system and no energy gained. So the new formula is 0 Energy

Δ Heat of Fusion. The given variables are the heat
capacity (Cp), the mass of water and the heat of fusion of water. The mass of ice cream is
weighed when given by the professor. To find the change of temperatures, the initial
temperature is taken when the mixture is distributed. The final temperature is 10 degree
Celsius. The same formula for the liquid nitrogen is used but instead of energy is going
