Questions and Answers
1.
This is a diagram of a of a ...
A.
Gas
B.
Solid
C.
Liquid
Correct Answer
B. Solid
Explanation The given diagram represents a solid. This can be inferred based on the options provided (gas, solid, liquid) and the fact that the diagram does not show any movement or flow, indicating a lack of fluidity.

2.
In which state can the particles only vibrate ?
A.
Solid
B.
Liquid
C.
Gas
Correct Answer
A. Solid
Explanation In a solid state, the particles are closely packed together and have a fixed position. They can only vibrate around their equilibrium positions, but they cannot move freely like in a liquid or gas. This is due to the strong intermolecular forces present in solids that hold the particles in a fixed arrangement. Therefore, the correct answer is solid.

3.
In which two states are the particles randomly arranged ?
A.
Solid and gas
B.
Liquid and solid
C.
Liquid and gas
Correct Answer
C. Liquid and gas
Explanation In the liquid and gas states, the particles are randomly arranged. In a liquid, the particles are close together but still able to move around and flow past each other, resulting in a random arrangement. In a gas, the particles are far apart and move freely in all directions, also leading to a random arrangement.

4.
Which two states don't have a fixed shape ?
A.
Gas and liquid
B.
Liquid and solid
C.
Solid and gas
Correct Answer
A. Gas and liquid
Explanation Gas and liquid are the two states of matter that do not have a fixed shape. In the gas state, particles are spread out and move freely, taking the shape of their container. In the liquid state, particles are close together but still able to move past one another, allowing liquids to take the shape of their container as well. Solid, on the other hand, has a fixed shape because its particles are tightly packed and locked into a specific arrangement.

All matter is made up of .....
A.
Air
B.
Cells
C.
Particles
D.
Fluid
Correct Answer
C. Particles
Explanation Matter is composed of tiny particles called atoms and molecules. These particles are too small to be seen with the naked eye. They are the building blocks of all matter, whether it is a solid, liquid, or gas. Therefore, the correct answer is particles.

The brownian motion was invented by Robert Brown
A.
True
B.
False
Correct Answer
A. True
Explanation The statement is true because Robert Brown, a Scottish botanist, discovered and described the phenomenon of Brownian motion in 1827. Brown observed the erratic movement of pollen particles suspended in water under a microscope, which was later named after him. This discovery contributed significantly to the understanding of particle movement and the kinetic theory of matter.

Robert Brown invented Brownian Motion in ________
Correct Answer 1827
Explanation The correct answer is 1827. Robert Brown discovered Brownian Motion in 1827. Brownian Motion refers to the random movement of microscopic particles suspended in a fluid due to the collision with the fluid molecules. Brown's observation of the erratic motion of pollen grains in water led to the discovery of this phenomenon, which later became an important concept in physics and chemistry.

The 3 states are......
A.
Solid
B.
Liquid
C.
Wood
D.
Gas
E.
Space
F.
Water
Correct Answer(s)
A. Solid B. Liquid D. Gas
Explanation The given question lists various states of matter and asks for the correct answer. The correct answer is "Solid, Liquid, Gas." This answer is correct because it accurately identifies the three primary states of matter. Solids have a fixed shape and volume, liquids have a definite volume but no fixed shape, and gases have neither a fixed shape nor volume. Wood, space, and water are not states of matter but rather specific examples or substances within those states.

9.
Which state can be compressed ?
A.
Solid
B.
Liquid
C.
Gas
D.
Option 4
Correct Answer
C. Gas
Explanation Gas can be compressed because its particles are far apart and have a lot of empty space between them. When pressure is applied, the particles can be forced closer together, reducing the volume occupied by the gas. This is why gases are highly compressible compared to solids and liquids, where the particles are already tightly packed and have less empty space between them.
