What two changes of state take place during distillation?
The two changes of state involved in freeze drying are melting and freezing.
What is produced when two Masses collide?
when two air masses collide it will produce weather changes such as wind, clouds, rain , snow, or tornadoes
What are two kind of changes in matter?
Two types of changes in matter are physical changes and chemical changes. Physical changes involve a change in appearance, such as a change in shape or state, without forming new substances. Chemical changes involve a rearrangement of atoms to form new substances with different chemical properties.
What two processes need heat to happen?
Melting, where a solid changes to a liquid state, and vaporization, where a liquid changes to a gas state, are two processes that require heat to happen. These phase changes involve absorbing thermal energy to break intermolecular forces holding the particles together.
What are two examples of changes in state that will generate an increase in molecular motion?
Melting ice to form liquid water or boiling liquid water to produce steam are two examples of changes in state that lead to an increase in molecular motion. In both cases, the added energy causes the molecules to move more rapidly and with greater freedom.
What two changes of state take place during distillation?
The two changes of state involved in freeze drying are melting and freezing.
Is mixing two substances and light is produced a chemical or physical change?
If light is produced when two substances are mixed, it is most likely a chemical change. Chemical changes involve the formation of new substances with different properties, whereas physical changes typically only affect the state or appearance of a substance without altering its chemical composition.
What two conditions can change the state of matter?
1) melting-solid state changes into liquid state and 2)freezing-liquid state changes into solid state
What two of state are involved in freeze drying?
The two changes of state involved in freeze drying are melting and freezing.
Has the state of Texas ever produced a president?
Yes they have produced two: Dwight D. Eisenhower and Lyndon B. Johnson.
What two changes of state does this process involve?
In order to know what two changes of state are involved in a process one needs to know what the process is.
Identify to changes of state that require energy to be used and two changes of state that require the release of energy?
Changes of state that require energy: melting (solid to liquid) and vaporization (liquid to gas). Changes of state that release energy: freezing (liquid to solid) and condensation (gas to liquid).

What two processes change water into a gaseous state?
In evaporation, a liquid such as water changes to a gaseous state. In sublimation, a solid such as ice changes driectly to a gas or vapor without going through a liquid state.
What is thermochromatic?
It is a combination of two words: thermo (meaning heat) and chromatic (having to do with color. A thermochromatic shirt (from American Apparel) changes color in accordance with the temperature of the cloth.
