Answer 1

Answer:

A)a hypothesis is an idea that hasn't been proven yet. If enough evidence accumulates to support a hypothesis, it moves to the next step — known as a theory — in the scientific method and becomes accepted as a valid explanation of a phenomenon.

B)Homogeneous mixture

1. It can't be separated out physically
2. 'homo' means the same
3. Example: a mixture of alcohol and water

Heterogeneous mixture

1. Heterogeneous mixture It can be separated out physically
2. Heterogeneous mixture It can be separated out physically 'hetero' means different
3. Heterogeneous mixture It can be separated out physically 'hetero' means different Example: a mixture of sodium chloride and sand

C) Sorry I don't know

D)Matter can exist in one of three main states: solid, liquid, or gas.

Matter can exist in one of three main states: solid, liquid, or gas.Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.

Matter can exist in one of three main states: solid, liquid, or gas.Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.Liquid matter is made of more loosely packed particles. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained.

Particles can move about within a liquid, but they are packed densely enough that volume is maintained.Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume. A gas can be compressed.
