Question

In school, Jarrett learned that salt lowers the freezing point of water. He wants to test this in a home experiment. He combines 1.0 grams of salt and 500 milliliters of water in a container. In an identical container, he pours 500 milliliters of water and does not add salt to it. What should Jarrett do next?

Answer 1

Put em somewhere pretty cold (like a freezer) and look at them from hourly intervals.

Answer 2

The correct answer is "Place both containers in a freezer, and record the temperatures at which they begin to freeze."

Step-by-step explanation:

Jarrett wants to compare the freezing temperature of pure water to that of salt water. To do this, he should place a sample of salt water and a sample of pure water in a freezer and record the temperatures at which they begin to freeze.
