malleability
One common physical property used to test the purity of metal is its melting point. Impurities can lower the melting point of a metal, so comparing the measured melting point to the known pure metal can indicate the presence of impurities. Other techniques include density measurements, spectroscopy, and X-ray diffraction.

One property he could measure is the density of the metal. Pure zinc has a specific density, so comparing the measured density to the known value for pure zinc can help determine the metal's purity. He could also perform a chemical test, such as reacting the metal with acid to see if it produces characteristic reactions of zinc.
The property commonly used to test the purity of a substance is its melting point. Pure substances have a specific melting point, while impurities typically lower and broaden this range. By comparing the observed melting point with the known melting point of the pure substance, one can assess its purity. Other techniques, such as chromatography or spectroscopy, may also be employed for more complex analyses.

For the acid test to determine the authenticity of gold, you typically use nitric acid. Nitric acid is used to test the purity of gold based on the reaction it produces with the metal.
A thermometer can be used to test the purity of a metal by measuring its specific heat capacity. Different metals have different specific heat capacities, so comparing the measured value to the known values for pure gold or iron can indicate the level of impurities present in the sample. A lower specific heat capacity than the known value may indicate impurities in the metal.
One physical test that can be used to distinguish between a metal element and a non-metal element is the ability to conduct electricity. Metals generally conduct electricity well, whereas non-metals are poor conductors. Another test is the luster or appearance - metals are usually shiny and have a metallic luster, while non-metals are dull in appearance.
You can test if yellow gold is real or plated by looking for markings like "14k" or "18k" indicating its purity. You can also do a simple acid test by scratching the gold on a stone and applying nitric acid to see if it reacts.

Purity tests are used to determine the extent to which a particular substance is what is claimed. A classic purity test for gold is nitric acid; if the item being examined reacts to the acid it is not gold, or at least not pure gold.
