Draw a picture of molecules in the form of solid liquid and gas. Solid Liquid Gas

Draw a picture of molecules in the form of solid liquid and gas.

What are the three characteristics of gas laws?

Temperature Pressure Volume

Looking at the data below, what is the relationship between Volume and Temperature? Can you think of an example?

Looking at the data below, what is the relationship between Volume and Temperature? Direct Relationship! As temperature increases, volume increases Example - balloon in erlenmeyer flask

Looking at the data below, what is the relationship between Temperature and Pressure? Can you think of an example?

Looking at the data below, what is the relationship between Temperature and Pressure? Direct Relationship! As temperature increases, pressure increases Example - can crush!

Describe the relationship between pressure and volume using the picture below.

As volume INCREASES, pressure DECREASES Inverse relationship

After looking at the relationships of these characteristics, draw in what each graph will look like.

What is Kelvin a measure of? Why is it so important?

What is Kelvin a measure of? Temperature It is important because it allows us to use very low temperatures without getting a negative number How to convert temperature in celsius

Ways to help solve! ●Write out all that you are GIVEN in the problem ●Figure out which 2 of the 3 chacteristics you are dealing with in the problem ●Find the correct formula that contains them

Boyle’s Law! Lab #52! Volume and Pressure

A sample of a gas has a volume of 150 mL when its pressure is atm. What will the volume of the gas be at a pressure of atm, if the temperature remains constant?

You decide to climb to the top of the tallest mountain, Mt. Everest. Before you are about to leave on your epic journey a friend gives you a balloon that was inflated to 800mL at sea level, where the pressure is 760 mmHg. You climb up to the top of Mt. Everest, 29,028ft above sea level, which has an average atmospheric pressure of 221 mmHg. What is the volume of the balloon at the top of Mt. Everest?

Charles’s Law! Temperature and Volume

A sample of a gas occupies a volume of 752 mL at K. What volume will the gas occupy if the temperature increases to K, if the pressure remains constant?

Cross multiply!

If you inflate a balloon to a size of 8.0 L inside where the temperature is K, what will be the new size of the balloon when you go outside where it is K?

Gay Lussac’s Law Temperature and Pressure

A sample of a gas has a pressure of 3.00 atm at K. What would the gas pressure be at °C, if the volume remains constant? Cross multiply!

A sample of a gas has a pressure of 3.00 atm at K. What would the gas pressure be at K, if the volume remains constant?

A bicycle tire is filled with air to a pressure of 100. psi at a temperature of K. Riding the bike on asphalt on a hot day increases the temperature of the tire to K. What is the tire pressure if the tire does not stretch?

A bicycle tire is filled with air to a pressure of 100. psi at a temperature of K. Riding the bike on asphalt on a hot day increases the temperature of the tire to K. What is the tire pressure if the tire does not stretch?

Ideal Gas Law

At what temperature would 2.10 moles of N 2 gas have a pressure of 1.25 atm in a 25.0 L tank?
