An ionic bond will form only if the sum of the energy changes is?
exothermic
What happens when a substance undergoes a physical change?
Physical changes refer to changes of state: solid to liquid or liquid to gas (or vice versa). The chemical structure of the substance does not change, only the amount of energy it contains.
Compare the total amount of energy before and after physical and chemical changes?
Physical Change-- Same amount of energy, but in different form Chemical Change-- Different amount of energy, and in a different form
What happens to heat during a change of state?
Heat increases the energy of in matter. This causes the movement of the particles making up the matter to speed up. The changes of state occur depending on the speed of the particles.
When you burn wood in a campfire what energy is change?
Burning wood is an example of chemical energy changing into heat and light energy. Energy is not destroyed, it simply changes from one form to another.
When energy changes from sound to light what happens to the energy?
It changes to another form.
When you increase energy in one form what happens to the energy in the other forms?
it changes form
When one form of energy changes into one or more other form energy what happens to the total amount of energy?
It remains constant
What happens to the total amount of energy when one form of energy changes to one or more forms?
It stays the same.
When one form of energy changes into one or more others forms of energy what happens to the total amount of energy?
It remains constant
What happens when a lamp plugged into an electric outlet is turned on?
the form of energy changes and the total of energy increases
What is it when a form of energy changes to another?
energy
What happens when you turn on a battery operated toothbrush?
Chemical energy changes to electrical energy which changes into mechanical energy
What happens when you turn on a battery-operated toothbrush?
Chemical energy changes to electrical energy which changes into mechanical energy
Does energy never changes from one form to another?
On the contrary, energy frequently changes from one form to another.
What are some ways that energy changes form in a car?
It changes electrical energy to thermal energy and light energy
When energy changes from one form to another form what does some of the energy change into?
kinetic energy :)
