1.
Any substance with mass that takes up space. All ______________ has mass, volume, and density.
Correct Answer
E. Matter
Explanation
Matter refers to any substance with mass that takes up space. It encompasses all materials and objects around us, including solids, liquids, and gases. Mass, volume, and density are all properties of matter. Therefore, matter is the correct answer to this question.
2.
The amount of space an object takes up.
Correct Answer
C. Volume
Explanation
Volume refers to the amount of space an object occupies. It is a physical quantity that measures the three-dimensional size of an object. In other words, volume tells us how much space an object takes up. It is commonly measured in units such as cubic meters or cubic centimeters. In the context of the given options, density refers to the mass of an object per unit volume, mass refers to the amount of matter in an object, and transparency refers to the ability of an object to transmit light. Therefore, volume is the correct answer as it directly relates to the amount of space an object occupies.
3.
The measure of how much mass is in a given volume.
Correct Answer
D. Density
Explanation
Density is the measure of how much mass is in a given volume. It is a physical property that describes the compactness of a substance. The higher the density, the more mass is packed into a given volume. Density is calculated by dividing the mass of an object by its volume. It is commonly used in various scientific fields, such as chemistry and physics, to determine the characteristics and behavior of different materials.
4.
The hue of an object; The smell of an object; How shiny a metal is;
Correct Answer
Odor, color, luster
Explanation
The correct answer is odor, color, luster. Odor refers to the smell of an object, color refers to the hue of an object, and luster refers to how shiny a metal is. These three characteristics are used to describe and differentiate objects based on their sensory properties.
5.
How well an object can be seen through; How hard an object is; How well a liquid dissolves; The ability to be flattened or bent without breaking.
Correct Answer
Transparency, hardness, resistance to breaking, dissolvability, malleability
Explanation
The answer provided lists different properties of objects: transparency, hardness, resistance to breaking, dissolvability, and malleability. Transparency refers to how well an object can be seen through, hardness refers to how hard an object is, resistance to breaking refers to the ability of an object to withstand force without breaking, dissolvability refers to how well a liquid can dissolve the object, and malleability refers to the ability of an object to be flattened or bent without breaking.
6.
The ability to transfer heat.
Correct Answer
B. Thermal conductivity
Explanation
Thermal conductivity refers to the ability of a material to transfer heat. It is a measure of how well a material conducts heat through it. Materials with high thermal conductivity can efficiently transfer heat, while those with low thermal conductivity are poor conductors of heat. This property is important in various applications, such as in the design of heat sinks, insulation materials, and cooking utensils.
7.
The ability to transfer electricity.
Correct Answer
A. Electrical conductivity
Explanation
Electrical conductivity refers to the property of a material to allow the flow of electric current. It is the ability of a substance to transfer electricity through its particles or atoms. Materials that are good conductors of electricity, such as metals, have a high electrical conductivity, while insulators have low electrical conductivity. This property is crucial in various applications, including the transmission of electricity in power lines and the functioning of electronic devices.
8.
What are the phases of matter?
Correct Answer
B. Solid; Liquid; Gas
Explanation
The phases of matter refer to the different states in which matter can exist. Solid, liquid, and gas are the three main phases of matter. In the solid phase, particles are tightly packed and have a fixed shape and volume. In the liquid phase, particles are close together but can move freely, taking the shape of their container. In the gas phase, particles are far apart and move rapidly, filling the entire space available to them. Density, volume, and mass are properties of matter, but they do not represent the phases of matter.
