Question | Answer |
---|---|
Shiny luster, malleable and a good conductor are physical properties of | metals |
Shiny or dull, brittle or malleable and a semiconductor are all physical properties of | metalloids |
Dull in luster, brittle and insulators are physical properties that belong to the | nonmetals |
An element that breaks into pieces when hammered has the physical property described as | brittle |
How an element transfers heat and electricity is called | conductivity |
A poor conductor of heat and electricity is known as an | insulator |
Insulators are categorized as | nonmetals |
Semiconductors are categorized as | metalloids |
Good conductors are categorized as | metals |
Gases belong to the group of | nonmetals |
How an element's surface reflects light is the physical property of | luster |
A physical property of metals which enables the metal to be pulled or stretched into wires is called | ductile |
Conductivity, malleability and luster are all | physical properties |
The most reliable test for determining if an unknown element is a metal, nonmetal or metalloid is the | conductivity test |
Electronics and computers are made with | semiconductors |
Mass divided by volume is the formula for | density |
Density is the amount of mass in a given | volume |
An object will sink in water if its density is _____ than 1g/cubic centimeter. | greater |
An object will float in water if its density is _____ than 1g/cubic centimeter. | less |
Oil and ice have densities that are less than water, so they will both | float |
Archimedes Principle involves finding volume using | displacement |
One gram/milliliter is equal to one gram/ | cubic centimeter |
Mass is 100g. Volume is 400 mL. To find density, you will _______________ 100 by 400. | divide |
