Answer 13

GAY-LUSSAC’S LAW

Question 14

DIFFUSION

Answer 14

GRAHAM’S LAW OF DIFFUSION

Question 15

THREE GAS LAWS COMBINED

Answer 15

COMBINED GAS LAW

Question 16

PROPONENT NG AVOGADRO’S LAW

Answer 16

AMADEO AVOGADRO

Question 17

1 mol gas = 22.414 L at STP

Answer 17

AVOGADRO’S LAW

Question 18

Shows the relationship among volume, pressure, temperature and number of moles of a gas

Answer 18

IDEAL GAS LAW

Question 19

GAS STOICHIOMETRY

Answer 19

• Volume to volume
• Volume to mass
• Mass to volume

Question 20

It states that for a given sample of gas at a constant temperature, its pressure is dependent upon the number of impacts made by the gaseous molecules per unit of time, or stated in another way, the volume of a confined gas is inversely proportional to the pressure at a constant temperature. This means that volume decreases with an increase in pressure, and increases when the pressure decreases.

Question 21

are the most thoroughly studied phase of matter

Answer 21

GASES

Question 22

the study of gases requires a concept known as the

Answer 22

STANDARD CONDITIONS OR STP

Question 23

The equations that express the relationships among P, V, T, and the number of moles (n), are known as the

Answer 23

GAS LAWS

Question 24

TEMPERATURE IS CONSTANT

Answer 24

BOYLE’S LAW

Question 25

It states that for a given sample of gas, the volume is directly proportional to absolute temperature. An increase in temperature causes the molecules to move faster and strike the walls of the container more forcefully.

Answer 25

CHARLE’S LAW

Question 26

CONSTANT PRESSURE

Answer 26

CHARLE’S LAW

Question 27

This is Boyle’s Law and Charles’ Law combined in an equation.

Answer 27

COMBINED GAS LAW

Question 28

states the equal volumes of gases, at the same temperature and pressure, have the same number of molecules. Hence, 1 liter of CO2 will contain the same number of molecules as 1 liter of NH3. For a given mass of an ideal gas, the volume is directly proportional to the number of moles (n), at constant pressure and temperature.

Answer 28

AVOGADRO’S LAW

Question 29

may be derived in a similar manner as the Combined Gas Law, using Avogadro’s Law, Boyle’s Law and Charles’ Law. An ideal gas is a hypothetical gas whose volume, temperature, and pressure behavior are described by the _______.

Answer 29

IDEAL GAS EQUATION
