Honors U4 Zone 5 Ideal Gas Law Check

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 amount of gas (n) in a gas sample. It is expressed as PV = nRT, where R is the ideal gas constant.

Front

What does the variable 'n' represent in the Ideal Gas Law?

Back

In the Ideal Gas Law, 'n' represents the amount of gas in moles.

Front

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

Back

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

Front

What conditions are considered Standard Temperature and Pressure (STP)?

Back

Standard Temperature and Pressure (STP) are defined as a temperature of 0 °C (273.15 K) and a pressure of 1 atm.

Front

How do you convert Celsius to Kelvin?

Back

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

Front

What is the relationship between pressure and volume in a gas at constant temperature?

Back

According to Boyle's Law, the pressure and volume of a gas are inversely related at constant temperature. As volume increases, pressure decreases, and vice versa.

Front

What happens to the volume of a gas if the temperature increases while pressure is held constant?

Back

According to Charles's Law, if the temperature of a gas increases while pressure is held constant, the volume of the gas will also increase.

Front

What is the significance of the term 'ideal' in Ideal Gas Law?

Back

The term 'ideal' refers to the assumption that gas particles do not interact and occupy no volume, which is only true under certain conditions.

Front

Why can't you use 22.4 L = 1 mol if not at STP?

Back

You cannot use 22.4 L = 1 mol if the conditions are not standard because the volume occupied by a gas varies with changes in temperature and pressure.

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.
