Question | Answer |
---|---|
Physical properties | characteristics that can be observed or measured WITHOUT changing the composition or identity of the substance |
Texture | the feel of an object |
Temperature | the amount of thermal energy a substance has Measured with a thermometer |
Luster | the quality of reflecting light from a surface or how shiny an object is |
Dull | the opposite of luster |
Color | the characteristic of substance with respect to light reflected by the substance |
Mass | the amount of matter in an object |
Weight | the force of an object due to gravity |
Volume | The amount of space an object takes up |
Melting, Freezing, Boiling Points | The exact temperature a substance begins to freeze, melt, or boil - It is different for every substance |
States of Matter | solid, liquid, gas and plasma |
Density | How tightly packed together the molecules are in a given space |
Density Formula | mass divided by volume (D = m/v) |
Ductile | describes a material that can be pulled out into a long wire. |
Malleable | The ability to be hammered & shaped - Think "mallet" or hammer |
Solubility | the ability of one substance to dissolve into another substance |
Insoluble | when a substance will NOT dissolve in to another substance |
Flexible | capable of bending without breaking |
Brittle | Easily broken; not flexible |
Conductivity | the ability to conduct (transfer) heat or electricity |
Magnetic | when an substance has a magnetic attraction |
Specific Heat | the amount of heat or energy required to increase the temperature of 1g of a substance by 1℃. |
Condensation | State/Phase of matter change from a gas to a liquid |
Vaporization | State/Phase of matter change from a liquid to a gas |
Fusion (melting) | State/Phase of matter change from a solid to a liquid |
Solidification (freezing) | State/Phase of matter change from a liquid to a solid |
Deposition | State/Phase of matter change from a gas to a solid |
Sublimation | State/Phase of matter change from a solid to a gas without becoming a liquid |
