Vocabulary A
How much stuff is inside an object. We measure it with a scale in grams (g). Think: how heavy does it feel?
What is mass?
The amount of a material that can dissolve in a liquid (solvent).
What is solubility?
Tiny pieces of something. (small portions of matter)
What are particles?
A connection between two or more things.
What is a relationship?
Name the alloy that we learned about. What two elements is it made up of?
What is brass? What are copper and zinc?
How much space an object takes up. To calculate (using a cube) calculate using this formula: area of the base x the height
What is volume?
A property of a material that measures how well heat energy can pass through it.
What is thermal conductivity?
A force that can attract or repel objects such as iron or steel.
What is magnetism?
A property of a material that measures how well electrical energy can pass through it.
What is electrical conductivity?
Name an element that has high thermal conductivity?
What is copper or Aluminum
How tightly the stuff is packed into the space; mass divided by volume.
What is density?
An object or substance that has mass and volume.
What is matter?
A material’s surface that partially reflects light so it has a sheen, or gloss.
What is luster?
Material that can dissolve.
What is soluble?
Name a material that has low thermal conductivity?
What is wood, plastic or stainless steel?
An observable or measurable characteristic of an object.
What is a property?
(from Latin conducere, meaning “to lead together.”) Examples: a metal wire that allows electricity to pass through it; a cooking pan that allows heat to pass through it.
What is conductivity?
A material that conducts electricity, heat, or sound poorly. It is not a conductor it is an.........
What is an insulator?
Separated into smaller pieces.
What is subdivided?
Name one of the elements that is heavy and dense and was used by plumbers for pipes? What is its 2 letter symbol?
What is lead? What is Pb?
(from latin “qualis” what kind) an observable description using your senses (words, not numbers). Examples: color, shine, rough or smooth, smell, hard or soft.
What is a qualitative property?
(from latin “quantus” how much) a measurable description using numbers and units; like mass, in grams (g), volume in centimeters (cm³) - for solid objects, in milliliters (mL) - for liquids, in degrees Celsius °C - for temperature.
What is a quantitative property?
Any change in an investigation that can affect the result.
What is a variable?
A property of a material that describes how well light or sound bounces off its surface.
What is reflectivity?
All matter in the universe is composed of these building blocks? How many of them are there?
What are elements? What are 118 elements?
