Homework Help: Chemistry

Posted by Angel on Friday, May 30, 2008 at 6:44pm.

This is a chemistry lab on boiling point, and I need some help with these questions!- Thanks!

(Info): You are going to take a trip. On this trip you will be stopping at different sites with varying altitudes. At each site you will compare the change in pressure and boiling point from the previous site to the new site.

Questions:

4a. You start at sea level on the beach in California. What would the atmospheric pressure be?

4b. What would the boiling point of water be?

5a. Now you've moved to Los Angeles, where the altitude is 87 meters above sea level. What has happened to the atmospheric pressure in comparison to when you were at sea level?


5b. What has happened to the boiling point of water?

5c. Would the atmospheric pressure be greater than or less than one atmosphere?

5d. Would the boiling point of water be greater than or less than 100°C?

6a. Now you find yourself on an airplane headed for Israel to visit the Dead Sea, which is below sea level. You have always wanted to visit there and now is your chance. What has happened to the atmospheric pressure?

6b. What has happened to the boiling point of water?

6c. Would the atmospheric pressure be greater than or less than one atmosphere?


6d. Would the boiling point of water be greater than or less than 100øC?

7a. While in Israel you run into a group of people who are headed for the Rocky Mountains. You have always wanted to climb to the top of Pike's Peak and decide to join them. Pike's Peak has an altitude of 4300 m. What has happened to the atmospheric pressure?

7b. What has happened to the boiling point of water?

7c. Would the atmospheric pressure be greater than or less than one atmosphere?
7d. Would the boiling point of water be greater than or less than 100°C?

7e. As you near the top of Pike's Peak, you feel your backpack becoming wet! The can of pop you put there when you were at the Dead Sea has exploded! Why do you think this happened?

Please help or will fail!
