The element silver has both physical and chemical properties, some of which do not change when the size of the sample changes. Which of these choices is a physical property that does not change when the size of the sample changes? flammability volume density reactivity with oxygen

I believe that the answer is density.

Reason being is because the density of an object does not change when an object changes size.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
