What is volume?
Correct Answer
A. The amount of space an object takes up
Explanation
The volume of an object refers to the amount of space it occupies. This means that it measures the three-dimensional extent of an object, including its length, width, and height. It is a measure of the physical space that an object occupies, regardless of the amount of matter it contains or the gravitational force acting on it.
2.
What is Mass?
Correct Answer
B. The amount of matter in an object
Explanation
Mass is a measure of the amount of matter in an object. It represents the total number of particles, such as atoms and molecules, that make up the object. Mass is an intrinsic property of an object and is independent of its location or the gravitational force acting on it. It can be measured in units such as grams or kilograms.
3.
What is weight?
Correct Answer
C. The pull of gravity on an object
Explanation
Weight is the force exerted on an object due to gravity. It is the measure of the gravitational force acting on an object's mass. The greater the mass of an object, the greater its weight will be. Weight is different from mass, as mass is the amount of matter in an object, while weight is the force experienced by that matter due to gravity. Therefore, the correct answer is "The pull of gravity on an object."
4.
What is used to find the volume of a regular shaped object?
Correct Answer
A. The formula LxWxH
Explanation
The formula LxWxH is used to find the volume of a regular shaped object. This formula represents the length, width, and height of the object, which are multiplied together to calculate the volume. This method is commonly used when dealing with objects that have a defined shape, such as a rectangular prism or a cube. By multiplying the dimensions together, the formula provides an accurate measurement of the object's volume.
5.
What is used to measure the volume of an irregular shaped object?
Correct Answer
B. A graduated cylinder
Explanation
A graduated cylinder is used to measure the volume of an irregular shaped object. This is because a graduated cylinder has markings on its side that indicate the volume of liquid it contains. By placing the irregular shaped object in the graduated cylinder and measuring the change in volume, the volume of the object can be determined. The formula LxWxH is not applicable in this case as it is used to calculate the volume of regular shaped objects. A triple beam balance and a platform scale are used to measure the mass of an object, not its volume.
6.
What is used to measure weight?
Correct Answer
D. A platform scale
Explanation
A platform scale is used to measure weight because it provides a flat surface where objects can be placed for measurement. The objects are placed on the platform and the scale displays the weight of the object accurately. This type of scale is commonly used in industries, grocery stores, and households for weighing various items ranging from small to large. It is a reliable and efficient tool for measuring weight accurately.
7.
Regular volume is measured in
Correct Answer
D. Cubic centimeters (cm^3)
Explanation
Regular volume is measured in cubic centimeters (cm^3) because it is a unit used to measure the volume of three-dimensional objects. Cubic centimeters are commonly used in scientific and mathematical calculations, as they provide a precise measurement of volume. Pounds, grams, and milliliters are units of weight and capacity, respectively, and are not suitable for measuring regular volume.
8.
Mass is measured in
Correct Answer
B. Grams (g)
Explanation
Mass is the measure of the amount of matter in an object. It is typically measured in grams (g) because it is a commonly used unit in the metric system. Pounds (lbs) is a unit of weight, not mass. Milliliters (mL) and cubic centimeters (cm^3) are units of volume, not mass. Therefore, grams (g) is the correct unit for measuring mass.
9.
Irregular volume is measured in
Correct Answer
C. Milliliters (mL)
Explanation
Irregular volume refers to the volume of an object that does not have a regular shape, making it difficult to measure using length, width, and height. Milliliters (mL) is a unit of measurement commonly used for liquids and irregular volumes. It is a more precise unit compared to pounds (lbs) and grams (g) which are used for measuring weight, and cubic centimeters (cm^3) which is used for measuring regular volumes. Therefore, milliliters (mL) is the correct unit for measuring irregular volume.
10.
Weight is measured in
Correct Answer
A. Pounds (lbs)
Explanation
Weight is measured in pounds (lbs). Pounds is a commonly used unit of measurement for weight in the United States and some other countries. It is a larger unit than grams and milliliters, making it more suitable for measuring larger objects or quantities. Cubic centimeters (cm^3) is a unit used to measure volume, not weight. Therefore, the correct answer is pounds (lbs).
