8. Mechanics:
The teacher will group the class into 4 (5 members
each).
He will give pieces of puzzle in each group and they are
task to solve the puzzle. They must unlock the hidden
message found at the back of each puzzle piece after
which, they must paste it on the board
The First group to unlock the message wins the game.
Goodluck!

10. Learning Objectives:
At the end of a 60 minute discussion, you will be able to;
a. State Charles's Law of Gas;
b. Give the mathematical formula involve in Charles’s law
c. Apply Charles’s Law in real life situation.
d. Solve problems involving Charles’s law of gas.
e. Appreciate the importance of Charles’s Law in one’s life.
16. Examples
What is the absolute temperature of a gas in
Kelvin if it is 250C?
= 298
What is the temperature of a gas in Kelvin if
it is in -500C?
= 223
18. Sample Problems involving Charles’s Law
A balloon initially has a volume of 0.4L and a
temperature of 200C. What will be the volume
of the balloon after it is heated at 2500C?
19. #2
A balloon has a volume of 3.0L at
270C. What is its temperature if it
expands to 6.0L?
