States Of Matter
A/ - Liquid
-Gas
-Solid
2. Atoms in a liquid are farther apart than theatomis in a liquid because?
A/ the particles in a gas move fast enough and independently
3. Give and example of something that has energetic molecules
A/ gas
4. What force pulls liquidstoward the grown?
A/ gravity
5. When a substance goes from a solid to a liquid
A/ melting
6. You may find plasma in a star? Yes or no? explain.
A/ Yes, is a gas-like substance consistingmainly of electrons, protons and helium ions. The combination of charged particles is what makes a plasma. They are sometimes called stellar plasmas.
7. Mention 3 examples that produce that thestate of matter change?
A/ -Melting
-Condensation
-Precipitation
8. If you have water in a glass and some molecules turn into gas it is called:
A/ Evaporation
9. Give threeexamples of plasma.
A/ -Star
-Fire
-Sun
10. What is the usually the total charge of plasma?
A/ consists of positive ions and free, negative electrons, the charges balance out.
11.How do waves transfer energy?
A/ by displaying molecules
12. How do waves express more force?
A/ by an earthquake, eruption and wind.
13. Energy storage called:
A/ incomplete proteins14. As the wave length increase the frequency?
A/ increase
15. Refraction occurs when a wave enters a new medium at an angles because?
A/
16. The way property is released to theheight of a wave is the?
A/ amplitude
17. What happen during constructive interference?
A/ Consider two waves that are in phase, sharing the same frequency and with amplitudes A1 and A2. Theirtroughs and peaks line up and the resultant wave will have amplitude A = A1 + A2.
18. Waves that don’t require a medium are?
A/ light an radio waves
19. How does sound travel?
A/ by...
