Data
Intial volume of water in the styrofoam cup (before the ice was added) (mL)
100
Final volume of water in the styrofoam cup (after the ice melted) (mL)
145
Volume of water due to melted ice (mL)

45
Mass (g) melted ice

45
Initial temperature (°C) of the water placed in the styrofoam cup
47.3
Minimum temperature (°C) after the ice was melted
45

Calculations
1. The amount of liquid water placed in the cup was _____100_______ mL. Assume that the density of water is 1.0 g/mL. What is the weight in grams of the liquid water?

Yes, because the density of water is 1

2. Calculate the temperature change.
47.3-4=43.5

3. Knowing that the specific heat of water is 4.184 J/g°C, calculate the total amount of heat released by the 100 ml of water as it cooled. This energy was used to melt the ice and then raise the temperature of the melted ice from 0 °C to the minimum temperature of the system.
