### Amount of mass in a known volume of an object.

Explanation
Density is the measure of the amount of mass in a given volume of an object. It is calculated by dividing the mass of the object by its volume. Density is a fundamental property of matter and can be used to identify substances and determine their composition. It is commonly expressed in units such as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

### The amount of space an object or substance takes up.

Explanation
Volume refers to the amount of space that an object or substance occupies. It is a measure of the three-dimensional extent of an object, indicating how much space it fills. In other words, volume quantifies the capacity or size of an object or substance. It can be calculated by measuring the length, width, and height of an object and multiplying them together. The unit of measurement for volume can vary depending on the context, such as cubic meters, liters, or cubic feet.

### The amount of matter in an object.

Explanation
Mass is a measure of the amount of matter in an object. It is a fundamental property of an object and is independent of its location. Mass is commonly measured in kilograms (kg) and can be thought of as the "heaviness" or "weight" of an object. It is different from weight, which is the force exerted on an object due to gravity. The greater the mass of an object, the more difficult it is to accelerate or move.

### A Measure of the pull of gravity on an object.

Explanation
Weight is a measure of the pull of gravity on an object. It is the force with which an object is attracted towards the center of the Earth or any other celestial body. Weight is directly proportional to the mass of an object, meaning that as the mass increases, the weight also increases. Weight is typically measured in units of force, such as pounds or newtons.

### The ability of matter to float in a liquid or gas

Explanation
Buoyancy refers to the ability of an object to float in a liquid or gas. When an object is placed in a fluid, it experiences an upward force called buoyant force, which is equal to the weight of the fluid displaced by the object. If the buoyant force is greater than the weight of the object, it will float. If the buoyant force is less than the weight, the object will sink. Therefore, buoyancy is the correct term to describe the ability of matter to float in a liquid or gas.

### A combination of two or more substances that do not form a new substance.

Explanation
A mixture refers to a combination of two or more substances that do not undergo a chemical reaction to form a new substance. In a mixture, the substances retain their individual properties and can be separated by physical means. This can include mixtures such as salt and water, air, or a salad.

### A mixture with one substance spread out so evenly in another substance that you cannot tell the two substances apart.

Explanation
A solution is a mixture where one substance is evenly dispersed and dissolved in another substance to the point where it is impossible to distinguish between the two. In a solution, the particles of the solute (the substance being dissolved) are evenly distributed throughout the solvent (the substance doing the dissolving), resulting in a homogeneous mixture. This means that the solution appears uniform and consistent, with no visible separation or distinction between the solute and solvent.

• 8.

### Another word for matter; something that has mass and takes up space.

Explanation
The given answer, "substance," is the correct answer because it accurately describes another word for matter. Matter refers to anything that has mass and takes up space, and substance is a synonym for matter. Therefore, substance is the appropriate term to use in this context.

Rate this question:

• 9.

### To form a solution with another substance.

Explanation
The word "dissolve" means to mix or blend a substance with another substance in such a way that the first substance becomes a part of the second substance, creating a solution. This process typically involves the solute (the substance being dissolved) being evenly distributed throughout the solvent (the substance in which the solute is dissolved). Therefore, the correct answer "dissolve" aligns with the given explanation, which states that the purpose is to form a solution with another substance.

Rate this question:

• 10.

### The change that happens to a substance during a chemical change. Something new is formed that can't be undone.

Explanation
A chemical reaction refers to the process in which a substance undergoes a change, resulting in the formation of something new that cannot be reversed or undone. This change involves the rearrangement of atoms and the breaking and forming of chemical bonds. Chemical reactions can involve the release or absorption of energy, such as heat or light. They are characterized by the formation of new substances with different properties from the original ones.
