From the deepest to most superficial: pia mater, arahnoid, dura mater
0-4 degrees Celsius, below which bacteria grow very slowly. This is the same as refrigerator temperature.

Parenchyma is the answer because whereas the other two, xylem and phloem are vascular tissues, parenchyma is a packing tissue.
Stars Like the Sun. When the core runs out of hydrogen fuel, it will contract under the weight of gravity. ... The upper layers will expand and eject material that will collect around the dying star to form a planetary nebula. Finally, the core will cool into a white dwarf and then eventually into a black dwarf.
Ok, particle is not a very nice word, no real sense of size associated with it
it can be a group of molecules like a speck of sand
referring to the molecules themselves
or refering to the atoms that make up the molecule
now in terms of phase change,
if we consider a speck- a group of molecules- then solids will expand when heated, however this definition falls flat in terms of phase change
ok, how about molecules, as molecules undergo phase change, the molecules in relation to each other will move apart from one another. Solid- molecules are bonded, Liquids- molecules are close and flow around each other, Gas- molecules are a significant distance from one another. But the increase in size when you heat up a molecule, i would have to say yes. adding heat increases energy which increases molecular vibration which would probably increase the overall average size to some unnoticeable degree.
now standalone atoms are just atoms, if you want to consider the electron cloud as size, then heating it up would negligibly cause the outer move outward. but it really depends on the scale of the question
