Correct Answer
D. Amount of matter in an objectExplanation
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.Rate this question:

Fahrenheit
- C.
Unit of temperature
- D.
Celcius
Correct Answer
D. CelciusExplanation
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.Rate this question:

- A.
Milli-
- B.
Centi-
- C.
Deci-
- D.
Kilo-
Correct Answer
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:
