When molecules move from one phase to another they are still the same substance. That vapor (or gas) can condense and become a drop of liquid water in the cooler air.

If you put that liquid drop in the freezer, it would become a solid piece of ice.

Matter is defined as anything that has mass and takes up space (it has volume). You might have a large object with very little mass such as a balloon filled with helium (He).

You should also know there is a difference between mass and weight. Words such as big, little, long, or short are used to describe volumes.

Chemical changes occur when the bonds between atoms in a compound are created or destroyed.

Generally, the basic chemical structure does not change when there is a physical change.It’s a fun state of matter when you remove almost all energy from a system.The scientists (Cornell, Ketterle, and Wieman) who worked with the Bose-Einstein condensate received a Nobel Prize for their work in 2001. It's all about the physical state and energy in the atoms and molecules. Physical properties of a solid often include "hard" and "brittle." Liquids are fluidy, move around a little, and fill up containers.You are able to smell the volatile compounds that are mixed in the air around you. If energy is added (increasing the temperature) or if energy is taken away (freezing something), you can create a physical change.Changing the pressure of a system is another way to create a physical change.Ceramic materials are usually made from soft clay that is heated up and then slowly cooled. However, the helium (He) inside the balloon is a gas.The clay becomes very hard because water (H Plasmas are highly energized gases that have lost their electrons. Hydrogen (H) and helium (He) ions float around the Sun with their electrons moving freely. Helium is a noble gas that has a very low atomic mass. If you place a glass of liquid water on a table, it will just sit there.If you place a glass of water in a vacuum chamber and lower the pressure, you can begin to watch the water boil and the water molecules move to a gas phase.Although its physical state may change because of different amounts of energy, its atomic structure remains the same. If you could add a second oxygen atom to a water (H). In reality, there are a variety of steps that go into creating hydrogen peroxide from water.Physical changes are related to changes in the immediate environment such as temperature, pressure, and other physical forces.
