Kinetic Theory/ States of Matter

Front

What is the kinetic theory of matter?

Back

The kinetic theory of matter states that all matter is made up of tiny particles that are in constant motion. The speed and energy of these particles determine the state of matter (solid, liquid, gas).

Front

What are the three main states of matter?

Back

The three main states of matter are solid, liquid, and gas.

Front

Which state of matter can be easily compressed?

Back

Gas can be easily compressed because its particles are far apart and have less attraction to each other.

Front

What is evaporation?

Back

Evaporation is the process by which liquid turns into vapor, requiring energy (endothermic change).

Front

What type of change is evaporation and why?

Back

Evaporation is an endothermic change because it requires energy to break the bonds between liquid particles.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often referred to as heat energy.

Front

How does temperature affect particle movement in matter?

Back

At higher temperatures, particles in an object move faster due to increased kinetic energy.

Front

What happens to gas particles when temperature increases?

Back

When temperature increases, gas particles move faster and spread apart, causing the gas to expand.

Front

What is the relationship between kinetic energy and temperature?

Back

Kinetic energy is directly related to temperature; as temperature increases, the kinetic energy of particles also increases.

Front

What is condensation?

Back

Condensation is the process by which gas turns into liquid, releasing energy (exothermic change).
