For a liquid to be useful in a thermometer, it should ?
a. flow very slowly from one place to the next
b. expand when it warms and contract when it cools
c. undergo a change of state within a narrow range of temperatures
d. adhere tightly to the material that makes up its container, such as glass or plastic

B

Explanation:

A: The speed in which the liquid moves is irrelevant, as long as it moves.

B: This will show the temperature: expansion -> bigger number -> hotter, and vise versa. You may already know that mercury expands and contracts with the change in temperature, without changing state. That is why the first thermometers used mercury.

C: No change of state is needed in a thermometer, and may actually cause it to break.

D: Adhering to a surface will cause the liquid to be unable to move, which shouldn't happen.

the answer is to check all of them! they all apply well at least i think so!
