100
The basic building blocks of matter. They can not be broken into smaller pieces with ordinary physical or chemical processes.
What are elements?
100
The different elements that are in a molecule of CO2.
What is 2?
100
The measure of the pull of gravity on an object.
What is weight?
100
A type of matter made up of a combination of elements.
What is a compound?
100
Why do most materials get smaller when they cool?
What is particles have less space between them?
200
The smallest particles of elements. They combine to form compounds.
What is an atom?
200
Look at the periodic table, what element is directly under the Flourine?
What is chlorine?
200
An object that takes up more space than another object has.
What is greater volume?
200
Different materials placed together but di not bond to form compound.
What is a mixture?
200
At this point a liquid turns into a gas.
What is boiling point?
300
No electrical charge inside the center of an atom's nucleus.
What is a neutron?
300
What are most elements made out of.
What is metals?
300
The density of an object that has a mass of 93 grams and a volume of 40 milliliters.
What is 2.3 g/mL?
300
A special mixture in which substances are spread out evenly and will not settle.
What is a solution?
300
Particles of salt arrange themselves in a regular geometric pattern forms this.
What is a crystal?
400
A positive charge. Usually found inside the nucleus of an atom.
What is a proton?
400
How are the elements organized in the table?
What is matter, solids, liquids and gases?
400
Compare the density of gold in a ring and in a necklace.
What is having the same density no matter what the gold is used in a ring or necklace?
400
The substance that dissolves in a solutions is called.
What is a solute?
400
What causes the phase change of water to form a gas?
What is heating?
500
The move around the protons and neutrons. It has a negative charge.
What is an electron?
500
Give two liquids on the periodic table.
What is bromine and mercury?
500
Explain how buoyancy and density are related to each other.
What is whether a material floats in a liquid (is buoyant) depends on the density of the material and the liquid. If the objects density is less than the liquid's density, it will float. If the object's density is greater than the liquid's density, it will sink.
500
Similarities and differences between mixtures and solutions.
What is elements or compounds are mixed together but they are not bonded to each other. In a mixture, different materials are placed together but do not form compounds. Simple mixtures can be easily separated. A solution is a special mixture in which substances spread out evenly and will not settle. In a solution, the solute is dissolved in the solvent. The amount of solute that can be dissolved in the solvent (solubility) is a property of the substance.
500
When does dew form?
What is when water vapor is cooled?
