NGSS.MS-PS3-4

Describe the particle motion in a gas. (Use lines or arrows to show how the atoms move.)

• Molecules are in continual motion (straight-line motion). Lots of kinetic energy. Far apart. Rapid movement of particles.

• Molecules are tightly packed and vibrate in fixed positions. Low kinetic energy. No movement between particles.

• Molecules are close together and slide past each other slowly. Moderate kinetic energy. Limited movement of particles.

• Molecules are stationary and form a rigid structure. No kinetic energy. No movement of particles.

Describe the particle motion in a liquid. (Use lines or arrows to show how the atoms move.)

• Molecules flow or glide over one another. More motion than solid but less than gas. Some movement of particles.

• Molecules are tightly packed and vibrate in fixed positions only.

• Molecules move freely in all directions at very high speeds with large spaces between them.

• Molecules do not move at all and remain completely stationary.

NGSS.MS-PS1-4

Describe the particle motion in a solid. (Use lines or arrows to show how the atoms move.)

• Molecules are held close together, vibrate in close proximity. Ordered arrangement. Slower movement of particles.

• Molecules are far apart, move freely and rapidly in all directions. No fixed arrangement.

• Molecules are loosely packed, slide past each other easily. Random arrangement.

• Molecules are stationary and do not move at all. Completely rigid and fixed.

What happens to the thermal energy of particles as a substance changes from solid to liquid to gas?

• Thermal energy increases as a substance changes from solid to liquid to gas.

• Thermal energy decreases as a substance changes from solid to liquid to gas.

• Thermal energy remains the same as a substance changes from solid to liquid to gas.

• Thermal energy first increases then decreases as a substance changes from solid to liquid to gas.

Molecules in a solid vibrate in place and are held close together.

• True

• False

What is kinetic energy?

• Energy due to the motion of atoms

• Energy that an object has because of its motion. Particles of matter are constantly in motion. The kinetic energy of matter depends on the substance and the state of matter.

• The average kinetic energy of the particles in a substance

• Energy that is transferred from higher temperature to lower temperature
