What is the physical property that is used to find if its pyrite or gold?
I would say streak (Is that a physical property?). Gold has a yellow streak, pyrite a very distinguishable greenish-black to brownish-black. [A streak is obtained by scratching a mineral (or rock) on a streak plate (a white plate made of porcelain (floor tile-like), with a hardness of around 6.5 (Mohs scale)] If streak is not a physical property I would say hardness: gold has a hardness of 2.5, pyrite of around 6. I'm sure there are other usuable physical properties, as density for ex.

What is the difference between streak and hardness?
A minerals hardness is its relative ability to scratch or be scratched by other minerals. Diamond, for instance, can scratch all other minerals because of its hardness. Streak is the color of the mineral when powdered. This is usually accomplished by the streak test (swiping the mineral across an unglazed porcelain surface) which reveals a mineral's streak color, which may differ from the color of the specimen being tested.
What is the difference between a scratch test and a streak test?
a streak test is a test wheree you rub a mineral across a streak plate to see the color of its streak, which is a better indentifying factor of the mineral than the external color. A scratch test is when you scratch a mineral to find out its hardness on the Mohs Scale of Hardness. This is also another useful identifying factor
What is the streak of sandstone and the hardness?
Streak and Mohs hardness are descriptive and identifying terms for minerals. Because sandstone could be composed of a multitude of different rock particles or minerals, a specific hardness or streak cannot be attributed to them.
