Explain why atoms move at different speeds depending on whether they are in liquid or solids

Answers

Atoms move a lot faster in liquid because the molecules have more room to move freely. On the other hand, in a solid the molecules are very tight together, giving them little room to wiggle around.

1. Rainbow (white light is split into its subsequent wavelengths)
2. Light enters through the cornea, is adjusted by the lens, the cones and rods of the retina are responsible for the perception of color and shadows, which are sent through the optic nerve to the occipital lobe of the brain.

3. Sound waves are intercepted by the pinna, travels through the auditory canal, reverberates on the eardrum, the vibrations travel through the ossicles of ear (hammer, anvil and stirrup), continuing to the cochlea and are sent through the auditory nerve to the brain.

4. A medium

5. Vibrations

6. All

7. Faster

8.Their kinetic energy increases

9. Conduction, convection and radiation

10. The heating of metals in the mantle, creates a current which slowly moves the plates above it.

If atoms are made up of smaller particles, such as protons, neutrons, and electrons, then why are atoms considered the smallest particles of an element?

Answers

Because all protons are the same, all neutrons are the same, and all electrons are the same, and all atoms of all elements are made of them, so the smallest particles of every element are the same particles.  It's only when some number of them get together and make an atom that the properties of an element begin to show up.

Let me try it like this, and see if this does anything for you:

All buildings are made of brick, cement, wood, glass, pipes, wires, etc.
But all bricks are the same, all cement is the same, all glass is the same, etc.
Houses, stores, shacks, skyscrapers, and hunting lodges are all made of them.
You don't know what kind of building you have, until some brick, some cement,
some wood and some glass all get put together.

Similarly, you don't know what kind of atom ... of what element ...you have, until
some protons, some neutrons, and some electrons get put together

A baseball falling toward a player's glove gains _____ energy and loses _____ energy. A. potential; kinetic B. kinetic; potential C. kinetic; chemical D. chemical; potential

Answers

Answer:

I think it's B it can not be C or D because it has nothing to do with chemical energy

Answer:

Your answer is B

Explanation:

When a ball falls it is gaining kinetic energy because it gains speed as it falls.Since its gaining kinetic energy it loses potential energy so ur answer is B :) hope it helps

Plz help me with this!

Answers

A conductor is something which allows electricity to pass through it
an example is a coin
An insulator is something which cannot allow electricity to pass through it
an example is plastic (or plastic cotton reel, plastic container ect.)
Static electricity is when you rub two things together to create static
