### What does SI stand for?

• A.

System of Worldwide measurements

• B.

Unit of volume

• C.

System for inches

• D.

A way in which is used to display data

A. System of Worldwide measurements
Explanation
SI stands for the International System of Units, also known as the metric system. It is a globally recognized system of measurements used in science, industry, and everyday life. The SI system provides standardized units for measuring quantities such as length, mass, time, temperature, and many others. It is used to ensure consistency and uniformity in measurements across different countries and disciplines.

### What is the unit of temperature called?

• A.

Volume

• B.

Fahrenheit

• C.

Kelvin

• D.

Celsius

C. Kelvin
Explanation
The unit of temperature called Kelvin is used in the scientific community and is based on the absolute scale of temperature. It is commonly used in physics and other scientific disciplines where precise temperature measurements are required. Unlike Celsius and Fahrenheit, Kelvin does not have negative values and is based on the concept of absolute zero, which is the lowest possible temperature.

### The prefix meaning 1000 is called?

• A.

Deci-

• B.

Centi-

• C.

Milli-

• D.

Kilo-

D. Kilo-
Explanation
The prefix "kilo-" is used to denote a factor of 1000. It is commonly used in the metric system to represent units that are larger than the base unit. For example, a kilogram is equal to 1000 grams. Therefore, "kilo-" is the correct answer to the question.

### What is the unit of time?

• A.

Minutes

• B.

Hours

• C.

Seconds

• D.

Years

C. Seconds
Explanation
The unit of time is seconds. Seconds are a commonly used unit of time in everyday life and scientific measurements. They are used to measure short durations or intervals, such as the time it takes for an event to occur or for an action to be completed. Other units of time, such as minutes, hours, and years, are derived from seconds and are used to measure longer durations. However, seconds are the fundamental unit of time and provide the most precise measurement for shorter intervals.

### What is mass?

• A.

The amount of space something takes up.

• B.

An explanation based on observations and experimentation

• C.

Pounds

• D.

Amount of matter in an object

D. Amount of matter in an object
Explanation
Mass is a fundamental property of matter that refers to the amount of matter an object contains. It is independent of the object's size or shape, and can be measured using a balance. Mass is different from weight, which is the force exerted on an object due to gravity. The correct answer, "Amount of matter in an object," accurately describes the concept of mass.

### What is the unit of length?

• A.

Inches

• B.

Meter

• C.

Centimeters

• D.

Millimeters

B. Meter
Explanation
The unit of length is meter. Meter is the standard unit of length in the metric system, and it is used to measure distances and dimensions. It is a fundamental unit of measurement and is commonly used in scientific, engineering, and everyday applications. Meter is a larger unit compared to centimeters and millimeters, and it is equivalent to 100 centimeters or 1000 millimeters.

### The unit of temperature used on thermometers is called, what?

• A.

Degrees

• B.

Fahrenheit

• C.

Unit of temperature

• D.

Celcius

D. Celcius
Explanation
The unit of temperature used on thermometers is called Celsius. This unit is named after the Swedish astronomer Anders Celsius, who first proposed the Celsius scale in 1742. It is commonly used in scientific and everyday contexts around the world, except for a few countries that still use the Fahrenheit scale. The Celsius scale is based on the freezing and boiling points of water, with 0 degrees Celsius being the freezing point and 100 degrees Celsius being the boiling point at sea level.

### The prefix meaning .001 is

• A.

Milli-

• B.

Centi-

• C.

Deci-

• D.

Kilo-

A. Milli-
Explanation
The prefix "milli-" is used to denote a factor of one thousandth, or 0.001. It is commonly used in the metric system to indicate a smaller unit of measurement. For example, one millimeter is equal to 0.001 meters, and one milligram is equal to 0.001 grams. Therefore, "milli-" is the correct prefix meaning 0.001.

Rate this question:

• 9.

### The prefix meaning 0.1 is

• A.

Milli-

• B.

Deci-

• C.

Centi-

• D.

Kilo-

B. Deci-
Explanation
The prefix "deci-" denotes a factor of 0.1. It is derived from the Latin word "decimus," meaning tenth. Therefore, when used as a prefix, "deci-" indicates a unit that is one-tenth of the base unit. In this case, "deci-" represents a factor of 0.1, making it the correct answer for the prefix meaning 0.1.

Rate this question:

• 10.

### Density is

• A.

Volume times mass

• B.

Mass times volume

• C.

Volume divided by mass

• D.

Mass divided by volume
