1.

### The density of an object is a ---

Explanation:
The density of an object is a physical property because it is a characteristic that can be measured or observed without changing the substance's chemical composition. Density is defined as the mass of an object divided by its volume, and it is a property that helps identify and classify different materials.
2.

### A pure substance always has ______ density when measured under _____ conditions.

Explanation:
A pure substance always has the same density when measured under the same conditions. This means that regardless of the amount or size of the substance being measured, its density will remain constant as the conditions under which the measurement is taken, such as temperature and pressure, remain the same. Therefore, both the substance's density and the measurement conditions are consistent, resulting in the answer "the same; the same."
3.

### A solution is a type of--

Explanation:
A solution is a type of mixture. A mixture is formed when two or more substances are combined physically but not chemically. In the case of a solution, one substance is dissolved in another, resulting in a homogeneous mixture where the particles of the solute are evenly distributed throughout the solvent. Solutions can be formed with various combinations of substances, such as solids dissolved in liquids, gases dissolved in liquids, or even gases dissolved in other gases. Therefore, the correct answer is mixture.
4.

### Weight is measured on a scale. Mass is measured on a --

Explanation:
Mass is measured on a balance. A balance is a device that compares the mass of an object to a known mass, typically using a lever or beam and a set of calibrated weights. It provides an accurate measurement of the mass of an object by comparing it to a standard mass. A scale, on the other hand, measures weight, which is the force exerted by an object due to gravity. While weight and mass are related, they are not the same thing, and therefore, mass cannot be measured on a scale.
5.

### Making skim milk is an example of ---

Answer: Using physical properties to separate a mixture
Explanation:
Making skim milk involves separating the fat content from the milk by using physical properties. Skim milk is made by removing the cream layer from whole milk, which is done through processes like centrifugation or gravity separation. These methods rely on the physical difference in density between the cream and the milk to separate them. Therefore, the correct answer is using physical properties to separate a mixture.
6.

### A person's _____ is different on a high mountain than it is at sea level.

Explanation:
Weight is a measure of the force of gravity acting on an object, and it depends on both mass and the strength of the gravitational field. Since the strength of gravity is weaker at higher altitudes, a person's weight will be slightly lower on a high mountain compared to at sea level. This is why people often weigh slightly less when they are at high altitudes.
7.

### Two similar looking substances are burned. One produces a red flame, and the other produces a yellow flame. This is an example of ---

Explanation:
The given scenario describes a situation where two similar substances are burned and produce different colored flames. This is a characteristic of a flame test, which is a method used to identify elements or compounds based on the color they emit when burned. The different colors of the flames indicate the presence of different elements or compounds in the substances being tested. Therefore, the correct answer is a flame test.
8.

### Other ____of substance, like color, size, and hardness, can be found without changing the substance into something else.

Explanation:
Physical properties refer to the characteristics of a substance that can be observed or measured without changing the substance into something else. These properties include color, size, and hardness. Reactivity, on the other hand, refers to how a substance reacts with other substances. Evaporation is a process where a substance changes from a liquid to a gas, and chemical properties refer to the characteristics of a substance that describe its behavior in chemical reactions. Therefore, physical properties are the correct answer as they can be determined without altering the substance's identity.
9.

### An object's ____ is the pull of gravity on the object

Explanation:
Weight is the correct answer because weight is the force exerted on an object due to gravity. It is a measure of the pull of gravity on the object and is influenced by the object's mass. Weight is different from mass, which is a measure of the amount of matter in an object. Solubility, volume, and matter are not related to the pull of gravity on an object.
10.

### A ____ has a definite volume but no definite shape.

Explanation:
A liquid has a definite volume because it takes up a specific amount of space, but it does not have a definite shape as it can take the shape of its container. Liquids are characterized by their ability to flow since the liquid particles have enough kinetic energy to slide past each other, and this allows liquids to take the shape of a container–unlike solids.
11.

### A ____ does not have a definite volume or a definite shape.

Explanation:
A gas does not have a definite volume or a definite shape because the particles in a gas are not tightly packed together and are free to move around. This allows the gas to expand to fill the entire space available to it, taking the shape of its container. Additionally, a gas does not have a specific volume because it can be compressed or expanded easily.
12.

### A _____ has both definite volume and shape.

Explanation:
A solid has both definite volume and shape because its particles are closely packed together and have strong intermolecular forces. This allows the solid to maintain a fixed shape and volume, as the particles are unable to move freely and are held in a rigid structure.
13.

### You can divide the mass of an object by its volume to find the object's ______.

Explanation:
Density is a physical property of an object that can be determined by dividing its mass by its volume. It represents the amount of mass per unit volume of a substance and is often used to describe the "heaviness" or "compactness" of an object. By dividing the mass of an object by its volume, we can calculate its density, which can provide valuable information about the object's composition and characteristics.
14.

### All material that takes up space is called.

Explanation:
Matter is the correct answer because it refers to any material that occupies space and has mass. Mass, weight, and volume are all properties of matter, but they do not encompass the entire concept. Solubility, on the other hand, is a specific property of matter related to its ability to dissolve in a solvent. Therefore, matter is the most comprehensive and accurate term to describe all material that takes up space.
15.

### The amount of material in an object is called the object's _____.

Explanation:
Mass refers to the amount of material or matter in an object. It is a fundamental property of matter and is measured in units such as grams or kilograms. Mass is different from weight, which is the force exerted on an object due to gravity. Density is the mass per unit volume, volume is the amount of space occupied by an object, and physical properties encompass various characteristics of an object including its mass.
16.

### You can measure the amount of space a solid object takes up, or the _____ of a solid object, by placing the object in a graduated cylinder with water and measuring how much water is displaced.

Explanation:
Volume refers to the amount of space that a solid object occupies. In this context, it is measured by placing the object in a graduated cylinder with water and measuring the amount of water that is displaced.
17.

### Chemical changes can turn substances into other substances. The ability of a substance to go through a chemical change is called _____.

Explanation:
Reactivity refers to the ability of a substance to undergo a chemical change, where it can react with other substances and transform into different substances. This involves the breaking and forming of chemical bonds, resulting in the creation of new compounds. Evaporation, condensation, and physical changes do not involve a change in the chemical composition of a substance, while combustibility refers specifically to the ability of a substance to burn. Therefore, reactivity is the most appropriate term to describe the ability of a substance to undergo chemical changes.
