Front

What are the three main states of matter?

Back

Solid, Liquid, Gas

Front

How are the particles arranged in a gas?

Back

Particles are far apart and move freely.

Front

What happens to the volume of a gas when temperature increases?

Back

The volume of the gas increases.

Front

What is the relationship between temperature and the movement of molecules in a gas?

Back

Higher temperature means molecules move faster; lower temperature means they move slower.

Front

What is required for a substance to change phases?

Back

Energy needs to be added or lost.

Front

What is the effect of temperature on the kinetic energy of gas molecules?

Back

As temperature increases, the kinetic energy of gas molecules increases.

Front

What is the definition of kinetic energy in the context of gas molecules?

Back

Kinetic energy is the energy of motion of the molecules.

Front

What happens to gas pressure when the volume decreases, assuming temperature is constant?

Back

Gas pressure increases.

Front

What is the ideal gas law equation?

Back

PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.

Front

What is the significance of the gas constant (R) in the ideal gas law?

Back

The gas constant relates the pressure, volume, and temperature of an ideal gas.
