How do molecules in a solid differ from those in a liquid or gas

Answers

Molecules in solids are packed a lot closer together than molecules in liquids and gases, so there is far less space between solid particles. Because of this, solid particles cannot move around quickly and freely like liquids and gases, instead they only vibrate so are fairly 'locked' into the same place, so solids have fixed volume and space.

An atom with an equal number of electrons and protons has no _________.A. reactivity
B. weight
C. charge

Answers

The answer would be C. charge because the protons, which are positively charged particles, and the electrons, negatively charged particles, balance each other out and the atom becomes of a neutral charge (or no charge)

Which of these is NOT a way, or a proposed way, to store nuclear fuel rods after they have been used in a nuclear reactor?

Answers

The question given above is not complete, the options attached to the question is given below:

A). Putting them in a deep pool of water

B). Burying them in a deep underground storage facility

C). Sending them on the shuttle to be suspended in space

D). Putting them in concrete/lead casks and sitting at thereactor site 

 ANSWER

The correct option is C.

There are many ways of storing spent nuclear fuel rods, these include: immersing them in deep pool of water, storing them in lead casks and burying them in deep underground storage. These forms of storage are utilized in order to protect people and the environment from the harmful radiations that radiate from these fuel rods. Spent fuel rods must never be exposed, therefore it is not possible to suspend them in space.
