What is the si unit used to measure the temperature of a substance? a. degree celsius b. degree fahrenheit c. gram d. kelvin e. mole

kelvin because it is the use to measure temperature

The correct answer is Option D.

Explanation:

Temperature of the substance is defined as the intensity of heat that a substance contains. It may also be defined as the degree of hotness or coldness.

S.I. unit stands for standard international unit.

Temperature is measured in various units such as Degree Celsius, Degree Fahrenheit and Degree kelvin.

The S.I. unit of temperature is Degree Kelvin.

Gram is the S.I. unit of Mass of the substance.

Mole is the S.I. unit of amount of substance.

Hence, the correct answer is Option D.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
