Solids will always behave the same upon heating regardless of their shape. The atoms are fixed to each other and thus can't shuffle around to make use of the inner space
Because when something heats it starts to develop into gas and the particles/atoms expand.
Oil does expand when heated and contracts when cooled.
Most things will usually expand because the atoms in it get heated and force the boundaries outward. Water is the exception which expands when frozen.
I'm guessing you mean a hollow point bullet, which do general expand when they hit something.

When matter is heated it will expand
Most substances expand when heated.
No, not all objects expand when heated. Most objects do expand when heated, but there are exceptions such as water between 0°C and 4°C, which contracts when heated. The expansion or contraction of an object when heated depends on its material properties.

Wood would expand about 0.3 millimeters if heated to 100 degrees
They expand
Matter expands when it is heated.
