Question Answer
properties of matterCharacteristics used to identify or describe a substance.
buoyancyThe ability of an object to float.
conductivityThe ability to allow heat or electricity to flow within the object itself.
ductileAn object can be heated and drawn out into a wire or thread form.
state of matterThe physical form of a substance at different temperatures, ie solid, liquid or gas.
freezing pointThe temperature at which a substance is in solid form. Pure water freezes at 32 degrees F or 0 degrees C. Salt water freezes dependent on it's salt content and is generally lower than 32 degrees.
solubilityThe ability of a substance to be dissolved in other substances. Salt and sugar are very soluble in water. This does not change the chemical make up of the substance.
physical properties of matterbuoyancy, conductivity, ductile, form/state of matter, and solubility.
chemical properties of matterChanges a substance undergoes when combined with elements like water, air, and fire.
flammabilityThe substance's ability to burn. Burning is a chemical reaction, because wood is permanently changed/transformed from wood to ash and gases.
acidic reactionA permanent change/transformation caused by exposure to acid that changes the chemical makeup of a substance.. Metals are reactive to acid
physical properties of silververy ductile and malleable
chemical properties of silvertarnishes with exposure to air containing sulfer
physical properties of potassiumsilvery white
chemical properties of potassiumcatches fire when exposed to water
What is a chemical reaction resutling in hydrogen gas?zinc reacting to exposure to hydrochloric acid.
What is a chemical reaction resulting in rust?iron combining with oxygen
What is a chemical reaction resulting in the mineral cuprite?copper combining with oxygen
Why is glass ductile?It can be heated and drawn out into minute threads to form fiber optics for lights.
This object is extremely buyant (.24 grams per milliliter and floats on to of wate.r)....cork
This object is extremely dense (8 grams per millileter) and water.iron
