The particles of a substance are arranged in a definite geometric pattern and are constantly vibrating. this substance can be in
1, the souls phase
2, the liquid phase, only
3, either the solid or the liquid phase
4, neither the liquid nor the solid phase

1.  Solid phase.

Explanation:

The  molecules in a solid are held in a definite pattern which is not true of a liquid or gas.

Solid State

Explanation:

in the solid state of matter substances have the particles arranged in a definite geometric pattern and are constantly vibrating, the main difference is the arrangement of the particles in a definite geometric pattern, compared to the liquid state in which particles take the shape of the conteiner where they are in.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
