Gas Laws Review

Front

What happens to the pressure of a gas when its temperature increases?

Back

The pressure increases.

Front

What is the new volume of a gas at STP if its temperature is raised to 273°C and pressure remains constant?

Back

5.0 L

Front

What happens to the volume of a helium balloon when placed in the freezer?

Back

The balloon's volume decreases.

Front

In a scenario where multiple flasks contain the same number of gas molecules at the same temperature, which flask has the lowest pressure?

Back

Flask 4.

Front

What describes the motion of a gas molecule?

Back

Molecules are far apart, move in constant random motion, and travel in a straight path.

Front

What is the ideal gas law equation?

Back

PV = nRT

Front

Define STP in terms of temperature and pressure.

Back

STP stands for Standard Temperature and Pressure: 0°C (273.15 K) and 1 atm.

Front

What is Boyle's Law?

Back

At constant temperature, the pressure of a gas is inversely proportional to its volume.

Front

What is Charles's Law?

Back

At constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin.

Front

What is Avogadro's Law?

Back

At the same temperature and pressure, equal volumes of gases contain the same number of molecules.
