because of the change of state of matter
ellipse is the shape of an egg
There is no "most" with respect to polygons. You could make a shape with a million sides, and then make a new shape with a million and one, and keep going forever.
Magnets also come in different strenghs
The differ in their mean and variance. The mean determines how far left or right they are along the variable axis (the x axis). The variance determines how narrow or wide the so-called bell shape is.
For a given area, the biggest volume you can enclose is a sphere. A sphere has the best volume-to-area ratio.
gas
Low density, no shape, high compressibility
It keeps it's shape
liquid has an indefinite shape and a definite volume,low compressibility and expands slightly
the basic difference is between the distance between the molecule which totally changes their shape and structure .......GAS: The molecules of gases are very far from each other therefore they neither have definite shape nor definite volumethey can be compressed easily and the rate of diffusion is highest in gasesLIQUID: The molecule are far but not very far from each other . As they are lit bit far therefore they dont have definite shape . they take the shape of their container. they have definite volumetheir compressibility is less than gasses, they can be compressed to some extent under high pressure . their rate of diffusion is less than gasses.....
They differ in shape ,size and even colour
Gases and liquid do not share the same compressibility property. In liquids, the molecules are approximately lesser compressed, that Is why they move around freely and does not have fixed shape. While gas is the most compressible and it doesn't have a shape.
Gases are characterized by their ability to expand to fill the container they are in, lack of definite shape or volume, low density compared to liquids and solids, and particles that are far apart and move freely. They also exhibit properties such as compressibility, diffusion, and low intermolecular forces.
Solids have a fixed shape and volume, with particles tightly packed together. Liquids have a fixed volume but take the shape of their container, with particles able to move past each other. Gases have neither a fixed shape nor volume, with particles far apart and moving freely. These differences impact properties like density, compressibility, and viscosity, as well as behaviors like diffusion and expansion.
In solid states, the particles are unable to move and there is no free space between them. This gives them a fixed shape and volume. As they cannot move, they cannot be compressed.
The most inefficient cell shape for diffusion is a large spherical cell, as it has a small surface area compared to its volume. This results in a slower rate of diffusion as molecules have a longer distance to travel to reach the cell's interior.
Veins have to carry blood for diffusion, therefore they muse be thin in order for diffusion to easily occur.
