What are the three main groups of matter?
Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles.

What are 3 differences between physical and chemical properties?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.

What are the 11 properties of water?
Unique properties of water
- Water is polar.
- Water is an excellent solvent.
- Water has high heat capacity.
- Water has high heat of vaporization.
- Water has cohesive and adhesive properties.
- Water is less dense as a solid than as a liquid.
What is the unique properties of water?
Summary. Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.

What is the importance of hydrogen bonding?
Hydrogen bonding is important in many chemical processes. Hydrogen bonding is responsible for water’s unique solvent capabilities. Hydrogen bonds hold complementary strands of DNA together, and they are responsible for determining the three-dimensional structure of folded proteins including enzymes and antibodies.
