Your question needs to be more specific for us to answer, for instance is the clay wet or dry, are you talking about geological formations of clay or a lump of potters clay.
If you apply hand pressure to a lump of potters clay and the clay is wet it will squeeze (deform) between your fingers. If the clay is dry it will be too firm to deform by hand but if placed in a vice it will crack.......etc.
If pressure is applied for long enough coal can become this
The only requirement is that the solid must have a slight vapor pressure under the applied conditions. Sublimation happens below triple point pressure.
Avogadro's principle can be applied when the temperature, volume and pressure are the same. This principle was named after Amedeo Avogadro.
it will stay the same size
Decreasing the pressure applied to the gas (apex)
the pressure and the temperature increases, and the volume is reduced.
pressure
decay
If a pressure greater than atmospheric pressure is applied to a solution or pure water, its water potential increases
It becomes metamorphic rock
is move themselves
An example is in brick-making. Pliable clay is formed into brick-shape, and put into a kiln. When the brick is removed from the kiln, it is a solid brick.
It is brittle
It is compressed and occupies a smaller volume.
They begin to move quicker
you get a hematoma
When a horizontal pressure is applied to rocks, the earth's surface will form lines that are perpendicular to the direction of the pressure. This can be compared to folds in a wrinkled rug lying on a floor.
