KMT, Pressure, Temp Flashcard

Front

What is the Kinetic Molecular Theory (KMT)?

Back

The Kinetic Molecular Theory (KMT) explains the behavior of gases in terms of particles in motion. It states that gas particles are in constant, random motion and that their collisions with each other and the walls of their container determine the gas's pressure and temperature.

How does temperature affect gas pressure?

Back

According to Gay-Lussac's Law, if the volume of a gas is held constant, increasing the temperature of the gas will increase its pressure.

Front

What happens to gas pressure when the volume decreases?

Back

According to Boyle's Law, if the temperature is held constant, decreasing the volume of a gas will increase its pressure.

Front

What is the relationship between the number of gas molecules and pressure?

Back

Increasing the number of gas molecules in a container, while keeping the volume and temperature constant, will increase the pressure.

Front

What is the definition of pressure in the context of gases?

Back

Pressure is defined as the force exerted by gas molecules colliding with the walls of their container, typically measured in units such as atmospheres (atm) or pascals (Pa).

What happens to a soccer ball's pressure when left outside in cold weather?

Back

The pressure inside the soccer ball decreases as the temperature drops, causing the ball to become flatter.

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume when temperature is held constant.

Front

What is Gay-Lussac's Law?

Back

Gay-Lussac's Law states that the pressure of a gas is directly proportional to its absolute temperature when volume is held constant.

Front

Why can gas molecules be easily compressed?

Back

Gas molecules can be easily compressed because they are far apart from each other, allowing them to be pushed closer together.

Front

What is absolute zero?

Back

Absolute zero is the theoretical temperature at which all molecular motion stops, defined as 0 Kelvin or -273.15 degrees Celsius.
