1. The relationship between temperature and volume
Charles's Law
The relationship between temperature and volume

2. How Volume Varies With Temperature
If we place a balloon in liquid nitrogen it shrinks:
So, gases shrink if cooled.

3. How Volume Varies With Temperature
Conversely,
if we heat a gas it expands
(as in a hot air balloon).

4. Check Your Understanding:
If the sun shining through windows heats the air in a sealed room, what happens to the air pressure in that room?
a It decreases.
b It will vary.
C It increases.
d It remains constant.

5. Temperature vs. Volume Graph5 10 15 20 25 30
Volume (mL)
25 mL at 22C
31.6 mL, 23.1 mL
Y=0.0847x
Temperature (C)

6. Check Your Understanding:
At constant pressure, how are the temperature and volume of a gas related?
a They are inversely proportional.
b They are directly proportional.
C They are constant.
d They are indirectly proportional.

7. Charles’s Law

8. When the temperature of a gas at a constant pressure is increased, its volume increases
At constant pressure, when the temperature of a gas is increased, what happens to its volume
T =
P = C
V =

9. When the temperature of a gas at a constant pressure is decreased, its volume decreases
At constant pressure, when the temperature of a gas is decreased, what happens to its volume
T =
P = C
V =

10. Check Your Understanding:
At constant pressure, when the temperature of a gas is decreased, what happens to its volume?
a It decreases.
b It will vary.
C It increases.
d It remains constant.

11. BOYLE’S LAW The relationship between pressure and volume

12. When the pressure of a gas at a constant temperature is increased, the volume of the gas decreases
If the temperature of a gas is constant, when the pressure is increased, the volume decreases
T= C P= V=

13. When the pressure of a gas at a constant temperature is decreased, the volume of the gas increases
If the temperature of a gas is constant, when the pressure is decreased, the volume increases
T= C P= V=
