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!

There are just two or three things you need to know in order to be able to answer all of these questions.

1. The pressure of the atmosphere is greater at low altitudes and lower at high altitudes; i.e., at the California location at sea level you would expect atmospheric pressure to be 1 atmosphere.

2. The definition of boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure; i.e., the boiling point of water is higher at low altitudes and lower at high altitudes. Said another way, the boiling point of water at sea level will be higher than it will be at Pikes Peak.

Thanks for the help!!! Any other answers would be much appreciated- THANK YOU SO MUCH! The lab is much easer to understand now!

On question 4b- what would the boiling point be, I can't figure it out? I'm not sure how to answer it!

What is the normal boiling point of water? Isn't it 100 degrees C. So if 4a is a California beach at sea level, then atmospheric pressure is 1 atmosphere (760 mm Hg)so 4b would be the normal boiling point of water which is 100 C.

Pike's Peak has an altitude of 4300 m. What has happened to the atmospheric pressure?

mmmm i did assignment not 2 long ago and it was hard so i wudnt mine given help but you would have to contact me @ 912 977 7299

Sure, I'd be happy to help you with these questions related to boiling point and atmospheric pressure!

4a. To determine the atmospheric pressure at sea level on the beach in California, you can refer to standard atmospheric pressure, which is approximately 1 atmosphere (atm). So, the atmospheric pressure would be around 1 atm.

4b. The boiling point of water at standard atmospheric pressure is 100°C or 212°F.

5a. When you move to Los Angeles, which is 87 meters above sea level, the atmospheric pressure will decrease compared to when you were at sea level. As you go higher in elevation, the atmospheric pressure decreases.

5b. As the atmospheric pressure decreases at higher altitudes, the boiling point of water also decreases. In other words, the boiling point of water would be less than 100°C.

5c. The atmospheric pressure in Los Angeles would be less than one atmosphere (1 atm) due to the higher altitude.

5d. Since the boiling point of water decreases at higher altitudes, the boiling point would be less than 100°C.

6a. When you are on an airplane heading for Israel, which is below sea level, the atmospheric pressure increases compared to when you were at sea level. As you descend to a lower altitude, the atmospheric pressure increases.

6b. With the increase in atmospheric pressure at lower altitudes, the boiling point of water also increases. The boiling point of water would be greater than 100°C.

6c. The atmospheric pressure in Israel, below sea level, would be greater than one atmosphere (1 atm) due to the lower altitude.

6d. Due to the higher atmospheric pressure, the boiling point of water would be greater than 100°C.

7a. As you climb to the top of Pike's Peak in the Rocky Mountains, which has an altitude of 4300 meters, the atmospheric pressure decreases further. At higher altitudes, the atmospheric pressure is significantly lower than at sea level.

7b. With the decrease in atmospheric pressure at higher altitudes, the boiling point of water also decreases. The boiling point of water would be less than 100°C.

7c. The atmospheric pressure at the top of Pike's Peak would be less than one atmosphere (1 atm) due to the higher altitude.

7d. Due to the lower atmospheric pressure, the boiling point of water would be less than 100°C.

7e. At higher altitudes, the atmospheric pressure decreases, making it easier for gases to expand. As a result, the pressure inside the can of pop (carbonated beverage) exceeded the external atmospheric pressure, causing it to explode. This phenomenon is due to the decrease in atmospheric pressure as you climb higher.
