A student is working with four beakers that each contains a clear liquid. Which set of procedures would be best to use to determine whether one of the beakers contains only distilled water? Group of answer choices

Observe volume, determine mass, observe color, determine pH

Observe odor, determine temperature, observe color, determine boiling point

Observe odor, determine pH, determine density, determine boiling point

Determine mass, observe volume, determine temperature, observe odor

Observe odor, determine pH, determine density, determine boiling point

Explanation:

The correct procedures that would be best to use to determine whether a beaker contains only distilled water would be to observe the odor of the liquid in the beaker, determine the pH of the liquid, determine the density, and then determine the boiling point of the liquid.

Water is generally odorless and has a pH of approximately 7 with a density of 1 kg/m3 and a boiling point of 100 . If the liquid in the beaker ticks all these conditions, then it can be established to be only distilled water.

a patient chooses to not take a beneficial medical treatment.

explanation:

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
