Sheila conducts an investigation to see how the amount of salt dissolved in water affects the density of the water. which statement best describes the correct plan for her procedure? the density and the amount of water are controls, and the amount of salt and the type of salt are variables. the amount of water and the amount of salt are controls, and the type of salt and the density are variables. the type of salt and the amount of water are controls, and the amount of salt and the density are variables. the type of salt and the density of water are controls, and the amount of salt and the amount of water are variables.

The correct procedure is "The type of salt and the amount of water are controls, and the amount of salt and the density are variables".

Explanation:

In the given problem, Sheila conducts an investigation to see how the amount of salt dissolved in water affects the density of the water.

Density measures how much mass in a given volume.

When the salt is dissolved in a water then the density of water increases.

The density is affected by the salinity and the temperature. Salinity describes how much salt is dissolved in water. When the salt is dissolved in the cold water then it becomes denser than the warm water without dissolved salt.

Therefore, the correct statement is "The type of salt and the amount of water are controls, and the amount of salt and the density are variables".

The correct procedure is "The type of salt and the amount of water are controls, and the amount of salt and the density are variables".
