Question

for each described liquid, determine the behavior of a hydrometer calibrated around the density of pure water.

Answer 1

Step-by-step explanation:

A hydrometer is a device used to measure the density of liquids, typically calibrated around the density of pure water. The behavior of a hydrometer in different liquids will depend on the density of the liquid compared to the density of pure water. Here are a couple examples of liquids and how a hydrometer calibrated around the density of pure water would behave:

1. Saltwater: Saltwater has a higher density than pure water due to the dissolved salt, so a hydrometer calibrated around the density of pure water would float higher in saltwater than in pure water.
2. Gasoline: Gasoline has a lower density than pure water, so a hydrometer calibrated around the density of pure water would float lower in gasoline than in pure water.
3. Honey: Honey is denser than water, so a hydrometer calibrated around the density of pure water would float higher in honey than in pure water.
4. Alcohol : Alcohol is less dense than water, so a hydrometer calibrated around the density of pure water would float lower in alcohol than in pure water.

It's important to note that the density of liquids can vary depending on temperature, pressure and chemical composition, so a hydrometer must be calibrated under specific conditions.
