1.
What is happening in this picture from left to right?
Correct Answer
C. Heat is being applied
Explanation
In the picture, it can be observed that there is a change occurring from left to right. The most logical explanation for this change is that heat is being applied. This is supported by the fact that the substance in the picture is transitioning from a dark place to a light place, which suggests that it is being heated and becoming brighter as a result.
2.
Which describes the motion of particles in a solid
Correct Answer
A. Compacted and slow
Explanation
The correct answer is "Compacted and slow." This answer accurately describes the motion of particles in a solid. In a solid, the particles are tightly packed together in a fixed arrangement, and they vibrate in place. This motion is relatively slow compared to the motion of particles in a liquid or gas, where the particles are more free to move and can move at higher speeds.
3.
As ___________ is added to a substance, its particles move faster
Correct Answer
heat
energy
Explanation
Though energy is an answer, remember that is can never be created or destroyed
4.
In order from slowest to fastest particles, the order of the states of matters are :__________, liquid, __________, ___________
Correct Answer
solid, gas, plasma
solid, liquid, gas, plasma
solid liquid gas plasma
solid gas plasma
Explanation
The correct answer is "solid, liquid, gas, plasma". This is because in a solid state, particles are tightly packed and have the least amount of energy, resulting in slow movement. In a liquid state, particles are loosely packed and have more energy, allowing them to move more freely. In a gas state, particles are further apart and have even more energy, causing them to move at a faster rate. Plasma, on the other hand, is an ionized gas where particles have extremely high energy levels and move at the fastest speed.
5.
The particles in solids have more energy than gases
Correct Answer
B. False
Explanation
This statement is false. In solids, the particles are tightly packed and have less kinetic energy compared to gases. The particles in gases have more energy and are more spread out.
6.
Plasma has the fastest moving particles
Correct Answer
A. True
Explanation
Plasma, often referred to as the fourth state of matter, consists of charged particles that move at extremely high speeds. These charged particles, such as electrons and ions, gain energy from the high temperatures in plasma and move rapidly, making plasma the state of matter with the fastest moving particles. Therefore, the statement that plasma has the fastest moving particles is true.
7.
Select all that apply for a liquid
Correct Answer(s)
B. Some Liquids include water and yogurt
D. Takes shape of container
Explanation
The given answer options correctly state that some liquids include water and yogurt, and that liquids take the shape of the container they are in. This aligns with the properties of liquids, as they have a definite volume but do not have a definite shape. The particles in a liquid are also fast and very mobile, allowing them to flow and take the shape of their container.
8.
Gases have no definite shape nor volume
Correct Answer
A. True
Explanation
Gases have no definite shape nor volume because their particles are in constant motion and spread out to fill the space available to them. Unlike solids and liquids, which have a fixed shape and volume, gases can expand or contract depending on the conditions they are subjected to. This is why gases can be compressed easily and take the shape of their container. Therefore, the statement "Gases have no definite shape nor volume" is true.
9.
What is the order of these different forms of water when relates to particle space?
Correct Answer
B. Compacted, semi-mobile, free
Explanation
The correct answer is "Compacted, semi-mobile, free." This order describes the different forms of water in terms of particle space. "Compacted" refers to solid ice, where water particles are tightly packed together. "Semi-mobile" refers to liquid water, where particles have more freedom to move but are still relatively close together. "Free" refers to water in its gaseous form, where particles have the most space and are free to move independently.
