Why do the particles in hot water move faster than the particles in cold water?

• There is more energy in this hot water

• There is less space for the particles to move in the hot water

• The cold water is easier for the particles to move around

• When water is hot, the particles don't need to move as much

This picture shows the particle motion of a solid. How would the picture be different if it showed a gas?

• The particles would has less room to move around (more dense)

• The particles would be moving slower

• The particles wouldn't be moving as much

• The particles would be less dense and be moving faster

These particles have low density, high energy, and lots of movement. Which phase of matter does this picture likely represent?

• Solid

• Liquid

• Gas

As the heat is removed from a gas, what happens to the particles in that substance?

• Particles move faster and get more dense

• Particles move around less and get less dense

• Particles move slower and get less dense

• Particle motion stays the same but the substance gets more dense
