9A Gas Laws

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume when the temperature is held constant. Mathematically, 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 the pressure is held constant. Mathematically, V1/T1 = V2/T2.

Front

What is the definition of Absolute Zero?

Back

Absolute Zero is the theoretical temperature at which a substance has minimum thermal energy, defined as 0 Kelvin or -273.15°C.

Front

What does 'inversely proportional' mean?

Back

Inversely proportional means that as one value increases, the other value decreases.

Front

If the pressure of a gas is doubled, what happens to its volume?

Back

If the pressure of a gas is doubled (while temperature remains constant), its volume is halved, according to Boyle's Law.

Front

What is the formula for calculating pressure using Boyle's Law?

Back

The formula is P1V1 = P2V2, where P is pressure and V is volume.

Front

What happens to the volume of a gas if its temperature increases while pressure remains constant?

Back

The volume of the gas increases, according to Charles's Law.

Front

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

Back

Pressure and volume are inversely related; as one increases, the other decreases.

Front

What is the standard unit of pressure in gas laws?

Back

The standard unit of pressure in gas laws is atmospheres (atm), but it can also be measured in pascals (Pa) or mmHg.

Front

What is the significance of 0 Kelvin in gas laws?

Back

0 Kelvin is significant because it represents Absolute Zero, the point at which molecular motion stops.
