Time | Temperature | Inches |
7:30 | 19 degrees | 2.5 inches |
8:00 | 2 degrees | 2.6inches |
8:30 | 2 degrees | 2.75 inches |
9:00 | 2 degrees | 2.75 inches |
10:00 + 1 tsp. salt | 0 degrees | 2.65 inches |
10:30 + 1 more tsp. salt Total: 2 tsp. salt | -5 degrees | 2.60 inches |
We measured out 1 cup of water and then poured it into a clear plastic container. Then we placed it into the freezer. Water is the smallest at room temperature.
At 10:00 when we added the salt it melted the ice and turned it into a slushy substance.
At 10:30 when we added more salt the more the ice melted and became more of a slushy material. But when we added more salt the temperature got lower or colder. We believe the amount of salt does affect the freezing point because according to our results the temperature lowered after we added more salt.
