Unit 2 Vocab Review

When a molecule has both slightly negative and slightly positive sides.

• Polarity

• Cohesion

• Pressure

• Dissolution

SC.912.L.18.12

When a solute is dissolved in a solvent, like water, you create this:

• Adhesion

• Salinity

• Solution

• Hydrogen bonds

Tags

SC.912.L.18.12

When a gas, liquid, or solid solute dissolves into a solvent and forms a solution, it's called:

• Solvent

• Dissolution

• Surface Tension

• Pressure

Tags

SC.912.L.18.12

These form between water molecules due to it's stronger polarity.

• Adhesion

• Halocline

• Hydrogen Bonds

• Solute

SC.912.L.18.12

When water molecules "stick" to each other, it is refereed to as:

• Cohesion

• Adhesion

• Density

• Polarity

Tags

SC.912.L.18.12

Water's ability to "stick" to other materials is caused by it's polarity and is called:

• Cohesion

• Pycnocline

• Solution

• Adhesion

Tags

SC.912.L.18.12

Water is able to create a dome above the rim of a glass due to it's:

• Dissolution

• Salinity

• Capillary Action

• Surface Tension

Tags

SC.912.L.18.12

When water climbs up fibers or pores and goes against the force of gravity using cohesion and adhesion:

• Capillary Action

• Surface Tension

• Polarity

• Density

Tags

SC.912.L.18.12

A feature that makes water a very weird substance, but allows life to live in the seas year round.

• Polarity

• Density

• Ice Expands as a Solid

• Hydrogen Bonds

• Density

• Salinity

• Pressure

• Cohesion
