2. Daily Reflection
Prompt: Will the boiling point of water be higher or lower in a high altitude city like Denver? Why?

3. The resistance of a liquid to flowing is called vi_______
scosity
Which has higher viscosity?
Syrup
Water

4. What is surface tension?
Surface ten______ is the result of an inward pull among the mole_______ of liquid that brings the molecules on the surface closer together.
Surface tension enables the ins______ to walk on the calm surface of a pond.
cules
ect

5. What is the temperature where a Solid turns into a Liquid called?
Melting Point

6. What is the temperature where a Liquid turns into a Gas called?
Boiling Point

7. Liquid water changing into water vapor is an example of va__________
porization

8. When vaporization takes place only on the surface of the liquid the process is called eva__________
poration

9. When vaporization takes place inside a liquid as well as at the surface, the process is called b_______
oiling

10. What happens to the Boiling Point when you go to higher elevation?
Boiling Point Depends on Air Pressure
In the city of Denver (1600 meters above sea level, water boils at 95 degrees Celsius)
That is why you have to boil longer at higher elevation.

11. Co_________ occurs when gas loses enough thermal energy to become a liquid.
ndensation
Occurs when a gas loses enough thermal energy to become a liquid: i.e. breathing onto a mirror.

12. limation
Sub_________ occurs when the surface particles of a solid gain enough energy to become a gas.
When the surface particles of a solid gain enough energy to become a gas without becoming a liquid.

13. What happens to Volume when Pressure is increased?

14. What happens to Volume when Pressure is decreased?
This is Boyle’s Law

15. Which cylinder has more pressure
Which cylinder has more pressure? What is happening to the volume of the cylinder with more pressure?

16. What is Boyle’s Law?
When the pressure of gas increased, the volume decreases.
When pressure decreased, the volume increases

17. What is happening to the volume as the temperature increases?
This is Charles’s Law

18. Which cylinder has higher temperature
Which cylinder has higher temperature? What is happening to the volume of the cylinder with higher temperature?
-65 C
250 C

19. What is Charles’s Law
When temperature increases, the volume of gas increases

20. Liquid water changing into water vapor is an example of va__________
porization

21. When vaporization takes place only on the surface of the liquid the process is called eva__________
poration

22. When vaporization takes place inside a liquid as well as at the surface, the process is called b_______
oiling

27. What happens to Volume when Pressure is decreased?
This is Boyle’s Law

28. Which cylinder has more pressure
Which cylinder has more pressure? What is happening to the volume of the cylinder with more pressure?

29. What is Boyle’s Law?
When the pressure of gas increased, the volume decreases.
When pressure decreased, the volume increases

30. What is happening to the volume as the temperature increases?
This is Charles’s Law

31. Which cylinder has higher temperature
Which cylinder has higher temperature? What is happening to the volume of the cylinder with higher temperature?
-65 C
250 C

32. What is Charles’s Law
When temperature increases, the volume of gas increases
