this question has really stumped me but i have tried doing it and have came up with some possible answers:

the following letters list some characteristics OF SOLIDS ACCORDING TO THE KINECTIC MOLECULAR THEORY.

A.) the particles are very closely packed together
B.) The particles are tightly bound to neighbouring particles
C.) The particles are arranged in a regular pattern
D.) the particles can only vibrate in their positions
E.) heat causes the vibration of the particles to increase

write the letter(s) of the charcteristics that can explain the following observations
a) solids do not flow or pour
b) solids cannot easily be compressed
c) as the temperature is increased many solids melt and become liquids
d) some solids form crystals

I only got these answers.. I know there is more but i have no clue! :::::

a.) A
b.) ?
c.) E
d.) ?

pleeeeeeese help me :)

Sorry -- but I don't know.

I think a is incorrect. I think B is a better choice.

I believe b is A.

I believe c is correct as you have it.

I believe d is C.

oh and you can have more than one letter for an answer..

thank you sooooo much :)

If each may have more than one answer and if an answer may be used more than once, I think you can pick others that are close; e.g., a might be A as well as B etc.

a) B C D

b) A C D

c) E B C

d) C A B D

Of course, I'll help you figure out the answers for the characteristics that explain the given observations. Let's go through each observation one by one:

Observation a) Solids do not flow or pour.
To explain this observation, we need to consider the characteristics that relate to how the particles are arranged and move in solids. According to the given characteristics:

A.) The particles are very closely packed together.
B.) The particles are tightly bound to neighboring particles.
C.) The particles are arranged in a regular pattern.
D.) The particles can only vibrate in their positions.
E.) Heat causes the vibration of the particles to increase.

Based on these characteristics, we can see that characteristics A, B, C, and D are relevant to the observation. Therefore, the answer would be:

a.) A, B, C, D.

Observation b) Solids cannot easily be compressed.
To explain this observation, we need to consider the characteristics that relate to the structure and movement of particles in solids. The relevant characteristics in this case are:

A.) The particles are very closely packed together.
B.) The particles are tightly bound to neighboring particles.

From these characteristics, we can see that both A and B relate to the observation. Therefore, the answer would be:

b.) A, B.

Observation c) As the temperature is increased, many solids melt and become liquids.
To explain this observation, we need to consider the characteristics that relate to the behavior of particles in solids when heat is applied. The relevant characteristic in this case is:

E.) Heat causes the vibration of the particles to increase.

From this characteristic, we can see that characteristic E explains why solids melt and become liquids when the temperature is increased. Therefore, the answer would be:

c.) E.

Observation d) Some solids form crystals.
To explain this observation, we need to consider the characteristics that relate to the arrangement of particles in solids. The relevant characteristic in this case is:

C.) The particles are arranged in a regular pattern.

From this characteristic, we can see that characteristic C explains why some solids form crystals. Therefore, the answer would be:

d.) C.

In summary, the answers to the characteristics that explain the given observations are:

a.) A, B, C, D.
b.) A, B.
c.) E.
d.) C.
