chemistry

These properties help identify unknown substances. Chemists can perform physical tests(that do not change the chemical structure of the substance) and take measurements to gather information. Comparing this information to known values for substances allows chemists to determine an unknown substance's identity. Water and sulfuric, acid are both clear, colorless & odorless liquids: Sulfuric acid's boiling point 337° C Water's boiling point 100° C Sulfuric acid's melting point 10°C Water's melting point O'C Density (more. dense objects Sink Name Answer Key Key Temperatures Phase Change a change state Melting Point The density of a substance is the amount of mass unit of volume per Every substance has its own unique density. Water's density: 1.00 g/ cm³ Sulfuric acid's density: 1.84 g/ cm³ the temperature at which 2 a liquid changes Boiling Point states to a gas the temperature at which a Solid changes state to a Tiquid you Describe a test could perform to determine whether an unknown substance is water or sulfuric acid: I could cool the liquid down to determine the temperature at which it freezes. If it freezes at 10.C it is sulfuric acid. If it freezes at oc it is water. Each Substance has a unique value for density. Melting and boiling temperatures can help
