Day 1
Lesson 3 Objective: – Understand the Kinetic Molecular theory but using the Combined gas law. Warm-Up: – How does the speed of the particles in a solid differ from the speed of the particles in a gas?
Kinetic Molecular Theory (KMT) 1.Small particles make up everything 2.These particles are in constant random motion 3.These moving particles collide with each other and their environment (“the walls of the container”) 4.When they collide no energy is lost
Temperature
Pressure!
Boyle Gay-Lussac’s
Boyle’s Law Practice 1.What is the final volume of a gas with an initial volume of 50ml, if the pressure increased from 600kPa to 900kPa? 2.What is the final volume of a gas with an initial volume of 100ml, if the pressure decreased from 500kPa to 250kPa?
Exit Ticket Which particles exert more pressure- those of a solid, liquid, or gas? How do you think adding thermal energy (heat) affects the pressure exerted by a gas?
Day 2
Lesson 3 Objective: – Understand the Kinetic Molecular theory but using the Combined gas law. Warm-Up: 1.The volume of a sample of oxygen is 300ml when the pressure is 1 atm and the temperature is 27C. What is the volume if the pressure is decreased to.5 atm and the temperature is increased to 227C? 2.Suppose that the pressure of 1L of gas is.5atm when the temperature is 200K. What is the volume when the temperature is increased to 600K and the pressure increases to.75atm?
Foldable You will create a foldable with 3 flaps. – Flap one will have the combined gas law and each letter defined – Flap two will contain 3 of my problems, worked out neatly – Flap 3 will contain 2 problems that YOU create. The foldable should have the word problem ONLY. The work and answer should be on a separate sheet of paper.
My word problems 1.The volume of gas collected when the temperature is 11C and the pressure is 710mmHg measures 14.8ml. What is the calculated volume of the gas at 20C and 740mmHg? 2. A 30L sample of gas exerts 200mmHg pressure at 10C. What volum,e does the gas have at 300mmHg and 25C? 3. At.5atm and 15C a sample of gas occupies 120l. What volume does it occupy at.250atm and 10C?

Day 3
Lesson 3 Objective: – Understand the Kinetic Molecular theory but using the Combined gas law. Warm-Up: 1.What is the relationship between pressure and volume of a gas if temperature is held constant? 2.If you quarter the volume of a container, how will the pressure change? 3.What is the relationship between temperature and volume of a gas? 4.What happens when you warm a balloon? Think about size, pressure and speed of particles? 5.Using what you now know about gas laws, explain how popcorn pops.
Demos- Explain why this happens. b20 b20 Your blood vessels are made of smooth muscle. Smooth muscles can dilate (making them bigger) or contract (making them smaller). How would this affect blood pressure? M9y4g M9y4g

Day 5
Lesson 2 Objective: – Understand phase change diagrams Warm-Up: 1.What change of state can you observe while watching a snowman melt? 2.What makes snow melt? 3.What happens to the particles as the snow melts? 4.Describe the three states of matter that are present when snow melts?
Exit Ticket What happens to particles of matter when you add thermal energy? In which state of matter would the particles of a substance have the most thermal energy? How do thermal energy and temperature differ?
Day 6
Lesson 2 Objective: – Understand phase change diagrams Warm-Up: 1.Why are sublimation and deposition unusual changes of state? 2.Explain sublimation and deposition. 3.What is the name of the state of matter change when a gas goes to a liquid. 4.There are two types of vaporization, one that happens in the liquid and one that happens at the surface. Identify both.
Phase change diagrams More practice
Exit Ticket Can you give an example of how matter is conserved during changes in state? When water loses thermal energy what state of matter will it turn into? What is this process known as? Where does this energy go? Describe thermal energy (KE and PE) as water goes from a liquid to a solid. How about as water goes from a solid to a liquid?
Day 7
