Transcript of Catalyst Briefly describe potential energy. What is its formula? Briefly describe kinetic energy....
Catalyst•Briefly describe potential energy. What is
its formula?•Briefly describe kinetic energy. What is its
formula?•Briefly describe conservation of energy.
What is an example where you would see it happening?
At which point in energy transformation will the system run out of energy?(Will there be enough energy after “said” events?)
Entropy is 1. The measure of disorder in
a system 2. The amount of non-usable
energy in a system
Write the following (Cornell notes style) into your INB
What is a system?
• A system is any object or set of objects going through a reaction
Law of Entropy•states that the entropy (disorder) in a system will always increase
Entropy = the measure of disorder in a systemLow Entropy = OrganizedHigh Entropy = Disorder, Disorganized
Entropy = the measure of disorder in a systemLow Entropy = OrganizedHigh Entropy = Disorder, Disorganized
Entropy = the measure of disorder in a systemLow Entropy = OrganizedHigh Entropy = Disorder, Disorganized
On your left-side (processing) page, draw the example (the two boxes) and write notes/captions
What does the Law of Entropy state? Law of entropy: in any
reaction, _______________________
What does that mean?
What does the Law of Entropy state? Law of entropy: in any reaction,
entropy will always increase
What does that mean? Some energy will always transform into a non-usable form

What’s happening to the energy?Energy is being transformed between PE and KE. However, becoming less with each bounce.Where is the energy going: what other forms of energy are part of this system?

What’s happening to the energy? The “lost” PE was transformed to non-usable energies: sound and thermal.

What does the Law of Entropy state? Law of entropy: in any reaction,
entropy will always increase
What does that mean? Some energy will always transform into a non-usable form
Re-usable energy: forms of potential and kinetic energy that can be re-used and transformed
Non-usable energy: energy that is lost to the universe
Law of entropy: in any reaction, entropy will always increase, meaning some energy will always transform into a non-usable form

Forms of Energy
•Energy spontaneously disperses from being localized to becoming spread out if it is not hindered from doing so.
•Example: Air in a high-pressure tire shoots out from even a small hole in its side to the lower pressure atmosphere.
•A hot pan contains lots of thermal energy. Apply the Law of Entropy and explain how it cools down.

REVIEW: SSP ½ sheet1. The law of entropy states that energy
tends to become _______. (useable? or unusable?)
2. In a system, is useable energy the input or the output?
3. Create a diagram showing the flow of energy for an electric fan.
