KMT & Matter

Front

What are the three main states of matter?

Back

Solid, liquid, gas.

Front

How does temperature affect the state of matter?

Back

Temperature influences the state of matter by changing the kinetic energy of particles, leading to phase transitions.

Front

What happens to particles when heat energy is removed?

Back

They slow down and get closer together.

Front

Which state of matter has the least kinetic energy?

Back

Solid.

Front

What occurs to particles during a phase change?

Back

The particles gain or lose energy, changing their movement and arrangement.

Front

Define kinetic energy in the context of matter.

Back

Kinetic energy is the energy of motion; in matter, it relates to how fast particles are moving.

Front

What is the effect of increasing temperature on gas particles?

Back

Gas particles move faster and spread further apart.

Front

What is a phase change?

Back

A phase change is a transition of matter from one state to another, such as solid to liquid.

Front

What is the relationship between kinetic energy and temperature?

Back

As kinetic energy increases, temperature increases.

Front

What happens to the arrangement of particles in a solid?

Back

Particles in a solid are closely packed and vibrate in fixed positions.
