PSMS Properties of Water

The curve in this meniscus is caused by the attraction between the water and the glass known as

• solute

• surface tension

• cohesion

• adhesion

Why does water move from the roots to the leaves of plants?

• Water is pushed by solutes
• Capillary action pulls the water molecules like a chain
• Water is pulled by gravity
• Water’s cohesion causes it to “pull” towards the leaves

Water is a universal solvent because it...

• It can be found anywhere
• It freezes when it gets cold
• floats when frozen
• Dissolves most substances

The fact that ice floats on liquid water is due to the fact that water's solid is ___________ than it's liquid form

• less polar
• more polar
• less dense
• more dense

What word describes when water is attracted to other substances?

• cohesion
• adhesion
• capillary action
• surface tension

The attraction that causes water and other liquids to form drops on thin films is called ________________. This is also water’s ability to be attracted to other water molecules.

• adhesion
• capillary action
• cohesion
• surface tension

Water beads up on the surface of a penny because of this property.

• Adhesion
• High Surface Tension
• Universal Solvent
• Changes in Density

Large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature. What is the reason for this phenomenon?

• Water is an acid.
• Water is a versatile solvent.
• Water has a high heat capacity.
•  Water acts as a buffer.
