FLASHCARD QUESTION

Front

What is the Ideal Gas Law?

Back

The Ideal Gas Law is a fundamental equation in chemistry that relates the pressure (P), volume (V), temperature (T), and number of moles (n) of an ideal gas: PV = nRT, where R is the ideal gas constant.

FLASHCARD QUESTION

Front

What is pressure in the context of gas laws?

Back

Pressure is the force exerted by gas particles colliding with the walls of their container, typically measured in atmospheres (atm), pascals (Pa), or millimeters of mercury (mmHg).

FLASHCARD QUESTION

Front

What is the relationship between pressure and volume in Boyle's Law?

Back

Boyle's Law states that at constant temperature, the pressure of a gas is inversely proportional to its volume: P1V1 = P2V2.

FLASHCARD QUESTION

Front

What does Charles's Law describe?

Back

Charles's Law states that at constant pressure, the volume of a gas is directly proportional to its absolute temperature (in Kelvin): V1/T1 = V2/T2.

FLASHCARD QUESTION

Front

What is Avogadro's Law?

Back

Avogadro's Law states that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules: V/n = k.

6.

FLASHCARD QUESTION

Front

Define absolute zero.

Back

Absolute zero is the theoretical temperature at which a system's entropy reaches its minimum value, corresponding to 0 Kelvin (-273.15 °C), where molecular motion stops.

7.

FLASHCARD QUESTION

Front

What is the significance of the gas constant (R) in the Ideal Gas Law?

Back

The gas constant (R) is a proportionality constant that relates the energy scale to the temperature scale in the Ideal Gas Law, with a value of 0.0821 L·atm/(K·mol) or 8.314 J/(K·mol).
