The relationship between temperature and volume
How Volume Varies With Temperature If we place a balloon in liquid nitrogen it shrinks: So, gases shrink if cooled.
How Volume Varies With Temperature Conversely, if we heat a gas it expands (as in a hot air balloon).
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.

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.
Charles’s Law
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 =
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 =
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.
bo. Yle’s law the relationship between pressure and volume
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=
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=
T and P no name…lets call it Sheffer’s Law T= P= V =C Directly Proportional
V and T Charles’s Law T = P=C V = • Directly Proportional
P and V Boyle’s Law T =C P= V = Inversely Proportional
