Chapter 14 – Gas Laws

Chapter 14 – Gas Laws

Chapter 14 – Gas Laws. Jennie L. Borders. Section 14.1 – Properties of Gases. Compressibility is a measure of how much the volume of matter decreases under pressure. Gases are compressible because the particles are far apart. Solids and liquids are not compressible.

Gay-Lussac’s Law

VIDEO. Gay-Lussac’s Law. P. There is a direct relationship between the temperature and pressure of a gas (if one increases so does the other) If volume is held constant: P 1 = P 2 T 1 T 2. Temperatures must be in Kelvin!.

Gas Laws

Gas Laws

Gas Laws. Ch 13.3. 4 variables affecting gas behavior. Pressure (P) Volume (V) Amount of gas (n) Temperature (T). Boyle’s Law. Pressure is inversely proportional to volume. (at the same temperature) P 1 V 1 = P 2 V 2 In a closed system, as volume goes down, pressure goes up.

Converting Pressures

Converting Pressures

Converting Pressures. 760 mm Hg = 760 torr 1 atm = 760 mm Hg 1 atm = 101.3 kPa 760 mm Hg = 101.3 kPa Converting Pressures: Convert 740 torr to kPa 740 torr (current pressure) x 101.3kPa (1 atm in kPa) /760 torr (atm in torr) (740)(101.3kPa /760) 740/760 is the fraction of 1 atm in torrs.

Kinetic Teori of Gas (Part 1)

Kinetic Teori of Gas (Part 1). By Ichwan Aryono. Boyle’s Law. If the temperature of gas in a container is maintained constant, the gas pressure is inversely propotional to its volume. P 1 V 1 = P 2 V 2 P : Gas Pressure ( N/m 2 or Pascal) V : Gas Volume (m 3 ). Gay Lussac’s Law.
