Science Flashcards
Element
A substance that cannot be broken down into any simpler substance
Compound
A substance whose particle is made of two or more different kind of Atom
Mixture
Two or more substances together
Substance
A type of matter defined by unique particle
What evidence can you observed that proves the chemical reaction has taken place
Evidence equals fizzy bubbles color sound temperature change phrase or form light
Explain how the modern. Parodic table of elements is organized and displayed
The periodic table is organized and displayed by left to right and of mass.
A student just arrived to our school and has not studied the periodic table. How are you explain to the student had the table is organized
USA to the student that the periodic table is organized by left to right and of mass
Who is the father of the periodic table
Dmitry ivanovick Mendeleyve
Compress
Reduced in volume as a result of applied pressure
Expand
And increase the volume
Gas
A phase of matter that has no definite shape or volume no ponds move freely freely can track compress expand
Liquid
Loose bonds move all around each other contract and expand
Solid solid
Contract right bonds
vibrate back-and-forth
Particle
The smallest piece of a substance that is still a substance
Sean investigated how it behaves in a close Syringe compressed air pushing the plunge it in as far as he could and then let go what happens to the pleasure plunger not pleasure
It can’t be compress and the particles pushed back up the plunger goes back where it was
Sean investigated how air behaves in a close syringe he compressed air by pushing the plunger in as far as he could like go explain why the air did not remain compress
That is not me make compress because it was a closest him the air cannot get out
Can gas because press why or why not
Yes gas can be compressed because there is space and air between The gas
Tif the syringe contained 100 particles, how many will there be after Sean pushes the syringe’s plunger down I’m like oh
There will still be 100 particles because the syringe is the close system and particles and air can’t get out
Compression
We do send a volume as a result of applied force
Contraction
The reduction of volume of a sample of matter as a result of cooling
Expansion
A increase the volume
Kinetic energy
Energy of motion
Describe how it particles move one trap in a balloon at room temperature
The air particles will still move about freely and at a rapid pace
What would happen to the air particle in the balloon if they were cooled
The particle would move slower less often and they would also hit with less force and come closer together
Explain what happened to air inside a close water bottle when it is heated
The particle would hit More often harder faster and spread out
Can solid liquid and gas on expand and contract explain
Yes because they would have an increase/decrease in kinetic energy heat
Explain what a liquid can contract and it can’t be compress like a gas
Because liquid has bonds and is touching and gas particles has space between them
Explain your energy transfers from one object that has the same temperature
It can’t because both object has equilibrium
Explain how energy transfers different temperature and also explain which direction does energy flow
The energy always flows from hot to cold. The direction energy flows is from hot to cold or high to low
Define Calorie energy transfer equilibrium heat and temperature
Calorie = The unit of energy that will rise 1 g of water 1 Celsius
Energy transferred = the movement of energy from one location to another
Equilibrium = the condition in which a system experimenting no net change
Heat = the form of energy related to KE
Temperature = the average kinetic energy of particles in a substance
Condensation
Phrase change of gas to liquid
Dissolve
Cause by liquid
Chemical interaction
A process during which start substance change into a new substance with different arrangements of Atom
Evaporation
To change phrase from liquid to solid
Melting
Solid to liquid
What is the difference between melting and dissolving
When you melts it increased cheat and dissolveing is caused by liquid
Every
Even
