Gas Values and Gas Laws

Vocabulary flashcards covering gas units, conversions at standard temperature and pressure (STP), and fundamental gas laws.

Boyle's Law

A gas law stating that pressure and volume are inversely related at constant temperature, represented by the formula $P_1 V_1 = P_2 V_2$.

Charles's Law

A gas law stating that temperature and volume are directly related at constant pressure, represented by the formula $\frac{V_1}{T_1} = \frac{V_2}{T_2}$.

Gay-Lussac's Law

A gas law stating that temperature and pressure are directly related when volume is constant, represented by the formula $\frac{P_1}{T_1} = \frac{P_2}{T_2}$.

Combined Gas Law

A gas law that combines Boyle's, Charles's, and Gay-Lussac's laws, expressed as $\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}$.

Ideal Gas Law

The equation of state of a gas, expressed as $PV = nRT$, derived from $\frac{P_1 V_1}{n_1 T_1} = \frac{P_2 V_2}{n_2 T_2} = R$.

Ideal Gas Constant ($R$)

The proportionality constant in the Ideal Gas Law, noted as having a value of $0.08205$.

Standard Temperature (STP)

The baseline temperature defined at standard temperature and pressure, equal to $273.15\,\text{K}$ ($0^\circ\text{C}$).

Standard Pressure (STP)

The baseline pressure defined at standard temperature and pressure, equal to $1\,\text{atm}$ or $101.3\,\text{kPa}$.

Molar Volume at STP

The volume occupied by one mole ($1\,\text{mol}$) of gas at standard temperature and pressure, equal to $22.4\,\text{L}$.

Celsius to Kelvin Conversion

The formula used to convert temperature to Kelvin: $K = ^\circ\text{C} + 273.15$.

Pressure Conversions

The equivalent units of pressure: $1\,\text{atm} = 101.3\,\text{kPa} = 760\,\text{mmHg} = 760\,\text{Torr}$.

Volume Conversions

The volumetric equivalence: $1000\,\text{mL} = 1000\,\text{cm}^3 = 1\,\text{L}$.
