In this Easy Peasy Chemistry lesson, we break down Specific Gravity in a simple and clear way!

After learning about density, it’s time to understand how substances compare to water. Why do some objects float while others sink? What does a hydrometer reading like 1.25 actually mean?

In this video, you’ll learn:

• What specific gravity really means
• How it is different from density
• Why water is used as the reference
• How floating and sinking are related
• How a hydrometer measures specific gravity
• Why specific gravity has no units.

This lesson is perfect for high school, college, pre-med, nursing, and engineering students.

Watch till the end to fully understand how scientists measure and compare densities in the lab.
