1) The particles would bounce off of each other and change their shape frequently.

2) You can either rapidly cool the material or constantly stir up the material. Cooling it rapidly causes the particles to cool so fast that they can't stick together and form clumps. The stirring of the material causes the material to cool at its own pace but it breaks up large clumps of the material.

1) Grains are the small particles that make up solids. When they don't fit together well they create fissures and imperfections in the solid that make the solid weaker. The smaller the grains are however the fewer fissures there are and the stronger the solid becomes.

2) In order to reduce imperfections there are a few methods that create smaller particles one is the Czochralski Growth method. It is when a rod is dipped in a high grade silicon and then twisted and pulled out and cooled. The silicon fills the imperfections in the metal and makes it stronger.

Invention: Explosives

Our idea is to create an explosive powder so fine that it allows for a larger explosion for a smaller amount of powder.

This is the orientation and general layout of the diffraction grating and the placement of those diffractions, we figured out that the spacing between the dots was attributed to the distances between the lines and estimated accordingly

2) Red- 1cm and 1.5cm on the respective diffraction gratings

Green - 1cm and 1.25cm on the respective diffraction gratings

160nm is the distance between the lines and 60 nm is the thickness of the lines

NaCl unit cell

This is my NaCl unit cell.

Length and Width in cm.: 4 X 4 X 4
nanometers: 4,000,000 X 4,000,000 X 4,000,000
angstroms: 40,000,000 X 40,000,000 X 40,000,000
meters: .004 X .004 X .004

Mass: .00031 grams
Moles: 5.3 e^-6 moles
Molecules in one cube of NaCl: 3.19 e18 molecules
Dimensions of a cube of NaCl: 629603nm X 629603nm X 629603nm
Number of unit cells in a cube: 4.5 e18 unit cells

Describing a mole of atoms and 10 nm

The purpose of this post is to describe 10 nm and 1 mole of atoms.

10 nanometers is a tiny measurement. A human hair is 40,000 nanometers wide and if we blew that size up to the size of an airsoft bb, which is 1/2 a centimeter wide, that would stretch it out to 20,000 centimeters which would stretch halfway around a running track.

1 mole of atoms is the number of atoms it takes to create a certain weight. Say you took a penny and a quarter and tried to weigh them on a bathroom scale. You can't do that effectively so instead you take 1,000 quarters and 1,000 pennies and weighed them on the bathroom scale. You can see a different weight for each of those weights. 1 mole equals the weight of both the pennies and the quarters at that selected number.
