A small cube of iron and a large flat sheet of iron contain the same volume. Which one will completely rust first? Explain why.
Hunter-Best [27]

The flat sheet will completely rust before the iron cube. Since they both have the same volume, the flat sheet has more surface area than the small cube. This means more particles are exposed on the flat sheet that can react in a chemical reaction.

As a real gas deviates from ideal gas behavior, the particles _____
Alik [6]

Answer:

Have some attraction towards each other

Explanation:

Gases deviate from the ideal gas behavior because their molecules have forces of attraction between them. At high pressure, the molecules of gases are very close to each other so the molecular interactions start operating and these molecules do not strike the walls of the container with full impact.

Hope this helps :-)

Have a great rest of your day or night!

Answer:

  1. Compress
  2. Fixed
  3. Melts
  4. Melting Point
  5. Freezing Point
  6. High
  7. Crystalline
  8. Lattice
  9. Unit cell
  10. Amorphous solids

Explanation:

Solids tend to be dense and difficult to <u>compress.</u>

They do not  flow or take the shape of their containers, like liquids do, because  the particles in solids vibrate around <u>fixed</u> points.

When a solid  is heated until its particles vibrate so rapidly that they are no longer  held in fixed positions, the solid <u>melts</u>.  

<u>Melting point</u> is the  temperature at which a solid changes to a liquid. The melting and <u>freezing point</u>  of a substance are at the same temperature.

In general,  ionic solids tend to have relatively <u>high</u>  melting points, while  molecular solids tend to have relatively low melting points.

Most  solids are <u>crystalline</u>

The particles are arranged in a pattern known  as a crystal <u>lattice</u>

The smallest subunit of a crystal lattice is the <u>unit cell</u>  

Some solids lack an ordered internal structure   and are called <u>amorphous solids.</u>
