What is the Ideal Gas Law?

Back

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

What does STP stand for in gas laws?

Back

STP stands for Standard Temperature and Pressure, which is defined as 0 degrees Celsius (273.15 K) and 1 atmosphere (atm) of pressure.

What is the value of the gas constant (R) in L·atm/(K·mol)?

Back

The value of the gas constant (R) is 0.0821 L·atm/(K·mol).

How do you convert Celsius to Kelvin?

Back

To convert Celsius to Kelvin, add 273.15 to the Celsius temperature: K = °C + 273.15.

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

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume when temperature and number of moles are held constant: P1V1 = P2V2.

Front

What is Charles's Law?

Back

Charles's Law states that the volume of a gas is directly proportional to its temperature (in Kelvin) when pressure and number of moles are constant: V1/T1 = V2/T2.

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.

Front

How do you calculate the number of moles from volume at STP?

Back

At STP, 1 mole of an ideal gas occupies 22.4 L. To find the number of moles, use the formula: n = V/22.4.

Front

What is the formula to calculate the volume of a gas using the Ideal Gas Law?

Back

The formula to calculate the volume (V) of a gas using the Ideal Gas Law is: V = nRT/P.

What is the significance of the Ideal Gas Law in real-world applications?

Back

The Ideal Gas Law is used in various applications, including calculating gas behavior in chemical reactions, engineering, and environmental science.
