What changes of state require energy?
Sublimation, melting, and vaporization are three changes of state which require energy.
When energy changes from one form to another often involved?
heat
What are changes of state that require energy?
Melting & evaporating.
What kind of form of energy is the change of position?
If the change of position is horizontal, then there's no energy involved. If it's a vertical change, then gravitational potential energy changes.
When energy is removed what does the decrease in energy causes the particles in that state to do?
When energy is removed, the particles involved lose kinetic energy-they slow down.
How does energy impact a change of state?
What kind of energy is involved when the matter changes state?
What energy changes are involved when an electric light shines?
electric energy changes to light & heat energy when light shines.
What changes of state require energy?
Sublimation, melting, and vaporization are three changes of state which require energy.
Is it true that energy changes only take place involved with chemical changes?
Yes Energy Kills you stay away from it
How substances changes from one state to the other state?
through changes of energy
Is energy always involved in physical or chemical changes?
Yes
What are two changes of states are involved in freeze-drying?
The two changes of state involved in freeze drying are melting and freezing.
What two of state are involved in freeze drying?
The two changes of state involved in freeze drying are melting and freezing.
What are three changes of state during which energy is absorbed?
The three changes of state during which energy is absorbed is: conduction, convection, & radiation.
What are the energy changes involved in cooking?
Chemical to heat to chemical to motion
When energy changes from one form to another often involved?
heat
Why do we say that chemical reactions always involve changes in energy?
Because they do. In fact, you can't get ANYTHING done without some energy changes involved.
