Observe the picture above. Bell Work: Observe the picture above. On page 36 of your composition notebook, write an “IF-THEN” statement that summarizes what is happening in the picture.
Each of the flasks below has a volume of 2 liters Each of the flasks below has a volume of 2 liters. What would 1 liter of air, 1 liter of water, and 1 liter brick would look like if they were in the flasks. This is the microscopic view….so particles.
This week’s goals: What we know so far… We know that all matter is made up of atoms. We know the particle arrangement for solids, liquids, and gases.

States of Matter The motion of atoms and molecules determines the _____ of matter. Density States Velocity Energy
States of Matter Gases can spread out and fill up a container because their molecular motion is _____ when compared to that of a solid. Slower Faster The same More dense
States of Matter Molecules in different phases of matter behave in different ways. Which of these statements best describes how molecules move in a liquid? Balloons being let go into the air A shopping cart filled with groceries A handful of coins thrown by a person Clothes being tossed around in a dryer
States of Matter How will a model of carbon dioxide gas differ from the model of the solid carbon dioxide shown? The gas particles will be farther apart. The gas particles will be larger. The gas particles will form bonds. The gas particles will react.

Today’s Topic: Behavior of Gases Chapter 8: Section 2
Today’s Goals: State the two different gas laws. Explain how temperature can affect the movement of gas particles. Describe the relationship between volume and pressure.
How much helium is needed to fill a parade balloon? It depends! The amount will change depending on the temperature that day.
The faster the particles are moving, the more energy they have. What is temperature? Temperature—a measure of how fast the particles in an object are moving…not just how “hot” something is The faster the particles are moving, the more energy they have.
On cold days, more gas is needed to fill the balloon. Hot vs. Cold If the temperature is hot, the particles hit the sides of the balloon harder. If the temperature is cold, the particles have less energy so they push the sides of the balloon softer. What’s the point??? On cold days, more gas is needed to fill the balloon.
Volume: Remember…volume is the amount of space something takes up. The volume of any gas depends on the container it’s in.
Pressure: Pressure—the amount of force exerted on a given area of surface HINT! Pressure is the number of times the gas particles hit the inside of their container.
Gas Behavior Laws Boyle’s Law—As the pressure of gas increases, the volume decreases by the same amount (Volume and Pressure)
Gas Behavior Laws Charles’s Law—If the temperature increases, the volume of gas also increases by the same amount. (Volume and Temperature)
Let’s sum it up… Boyle’s Law…describes the relationship between VOLUME and PRESSURE. Charles’s Law…describes the relationship between VOLUME and TEMPERATURE.
