An inch is
Correct Answer
A. Bigger than a centimeter
Explanation
An inch is bigger than a centimeter because the inch is a larger unit of measurement than the centimeter. In the metric system, 1 inch is equal to 2.54 centimeters. Therefore, any measurement in inches will be greater than the equivalent measurement in centimeters.
2.
One inch is equal to
Correct Answer
D. 2.54cm
Explanation
One inch is equal to 2.54cm. This is a well-known conversion factor used to convert measurements between the imperial system (inches) and the metric system (centimeters). It is derived from the definition that 1 inch is equal to exactly 2.54 centimeters. Therefore, when converting inches to centimeters, the value is multiplied by 2.54.
3.
Which of these is bigger than a millimeter?
Correct Answer
D. All of these
Explanation
All of these options (centimeter, feet, meter) are bigger than a millimeter. A millimeter is a unit of length in the metric system, and it is equal to one thousandth of a meter. A centimeter is equal to one hundredth of a meter, which is bigger than a millimeter. Similarly, a foot is approximately 0.3048 meters, and a meter is equal to one meter, both of which are also bigger than a millimeter. Therefore, all of these options are correct.
4.
Temperature is measured in
Correct Answer
B. Celsius
Explanation
Temperature is measured in Celsius. Celsius is a widely used unit for measuring temperature in the metric system. It is based on the Celsius scale, which sets the freezing point of water at 0 degrees Celsius and the boiling point at 100 degrees Celsius at standard atmospheric pressure. This scale is commonly used in scientific and everyday applications around the world, making it the correct answer for measuring temperature.
5.
Liquid is measured in
Correct Answer
B. Liter
Explanation
Liquid is measured in liters because liters are a unit of volume commonly used for measuring liquids. Kilograms are used to measure mass, centimeters and millimeters are used to measure length or distance. Therefore, liters is the correct unit of measurement for liquids.
6.

10.
Height can not be measured in
Correct Answer
B. Liters
Explanation
Liters is a unit of volume and is used to measure the capacity of liquid substances. Height, on the other hand, is a measurement of distance and is typically measured in units such as meters, centimeters, or feet. Therefore, it is not appropriate to measure height in liters as it does not represent a distance measurement.
