This state of matter keeps its shape and doesn’t flow.
A solid.
Ice melting into water is this kind of change.
Melting.
Adding this makes particles move faster.
Heat.
The air we breathe contains this essential gas that allows us to live and function.
Oxygen.
This term describes water molecules sticking to each other.
Cohesion.
This state of matter takes the shape of its container but keeps the same volume.
A liquid.
Water turning to ice is called this.
Freezing.
When particles move faster, this happens to the substance’s temperature.
Gets hotter or increases.
Matter is made of these tiny building blocks.
Atoms, particles, or molecules.
This term describes water sticking to other surfaces, like glass.
Adhesion.
This state spreads out the farthest to fill any container completely.
A gas.
Liquid water turning into water vapor.
Evaporation.
Taking heat away makes particles move this way.
Closer or slower.
This state of matter has particles packed tightly and vibrating.
Solid.
This property allows some insects, like water striders, to walk on water.
Surface tension.
This term describes when a solid changes directly into a gas.
Sublimation.
Water vapor cooling and turning back into liquid droplets.
Condensation.
The energy of motion in particles is called this.
Kinetic energy.
The state of matter with particles moving freely and only slightly far apart.
Liquid.
These two forces work together to allow water to form round droplets on a penny.
Cohesion and surface tension.
This strange state of matter was barely discussed this unit, but it has extremely high energy and is found in stars.
Plasma.
This term describes when a gas changes directly into a solid.
Deposition.
The temperature at which a liquid begins to boil is called the ______________________.
Boiling point.
The amount of matter in an object.
Mass.
The bond between water molecules.
Hydrogen bond.
