1. What is density?
- A.
How much mass is in a given space
- B.
How much matter is in a given space
Correct Answer
A. How much mass is in a given spaceExplanation
Density is a measure of how much mass is present in a given space. It is calculated by dividing the mass of an object by its volume. The answer choice "How much matter is in a given space" is incorrect because matter refers to anything that has mass and takes up space, whereas density specifically refers to the mass of an object in relation to its volume.Rate this question:

2. What are the three main states of matter?
- A.
Solid, liquid, and gas
- B.
Solid, nitrogen, and liquid
Correct Answer
A. Solid, liquid, and gasExplanation
The three main states of matter are solid, liquid, and gas. In the solid state, particles are closely packed together and have a fixed shape and volume. In the liquid state, particles are still close together but can move and flow, taking the shape of their container. In the gas state, particles are far apart and move freely, filling the entire space available to them. The answer "Solid, liquid, and gas" correctly identifies these three states of matter.Rate this question:

3. When sugar is added to water and mixed together it is an example of what kind of change?
- A.
A physical change
- B.
A chemical change
Correct Answer
A. A physical changeExplanation
When sugar is added to water and mixed together, it dissolves and forms a homogeneous solution. This process does not involve any chemical reactions, as the sugar molecules remain intact and do not change their chemical composition. Therefore, this is an example of a physical change, where the state or appearance of a substance is altered without any new substances being formed.Rate this question:

4. I put a cup of water in the frezzer and take it out the next day and observe it is now ice. What kind of change is this?
- A.
A chemical change
- B.
A physical change
Correct Answer
B. A physical changeExplanation
The change of water from a liquid state to a solid state (ice) is a physical change. In a physical change, the substance retains its chemical composition, but there is a change in its physical properties such as shape, state, or size. In this case, the water molecules rearranged themselves and formed a solid structure, but the chemical composition of water (H2O) remained the same.Rate this question:

5. When a egg is fried on a pan, the egg represents what?
- A.
A chemical change
- B.
A physical change
- C.
That it is flammable
Correct Answer
A. A chemical changeExplanation
When an egg is fried on a pan, it undergoes a chemical change. This is because the heat causes the proteins in the egg to denature and coagulate, resulting in a permanent change in the composition and structure of the egg. This is different from a physical change, where the substance may change form or state but its chemical composition remains the same. The fact that the egg is flammable is not relevant to the question and does not determine whether it undergoes a chemical or physical change.Rate this question:

6. When you are identifying the hardness of a mineral you use what?
- A.
A math book
- B.
A ruler and a pencil
- C.
The Mohs scale
Correct Answer
C. The Mohs scaleExplanation
The correct answer is "The Mohs scale." The Mohs scale is a scale used to measure the hardness of minerals. It consists of a series of 10 minerals, with each mineral being assigned a number from 1 to 10 based on its hardness. By comparing the hardness of an unknown mineral to the minerals on the Mohs scale, one can determine its hardness. Using a math book or a ruler and a pencil would not provide the necessary information to identify the hardness of a mineral.Rate this question:
