## Questions

### Subject: French

When do I use the "passé simple" tense in French?

The "passé simple" is a literary tense that is used predominantly in formal writing and very formal speech.

### Subject: Chemistry

If you pour a handful of salt into a glass of water, will the water level go up or down?

The water level will actually go down as long as the solution is not supersaturated since the force of attraction between the water molecules and the salt ions decreases the total volume of the solution

### Subject: Algebra

Am I ever going to use Algebra outside the classroom?

Algebra is not only about equations and finding the value of x, but it is also about learning to think logically and to apply math to everyday life. We are surrounded by numbers everyday and everywhere. Whether you're shopping and trying to figure out the price of an item after a 20% sale, or you want to calculate your final course grade, you are actually using the principles and the thought process you learned in algebra. The real-life applications of this beautiful subject are infinite!
