Atomic Math
The smallest unit of matter.
What is an atom?
The amount of matter packed into a space.
What is density?
What atoms and molecules of solid rock DON'T do.
What is move?
Melted wax is an example of this change.
What is freezing?
Changing the number of protons of an element creates this.
What is a new element?
The amount of space an object occupies is called this.
What is volume?
The calculation to find the volume of a rectangle prism, like a juice box.
What is length x width x height
A substance with no fixed shape, but a fixed volume.
What is liquid?
The temperature at which a solid becomes a liquid.
What is melting point?
Changing the number of electrons of an element creates this.
What is ion?
The amount of atoms in an object is called this.
What is mass?
The density of a rectangular block of metal that weighs 480g, and has dimensions of 8cm x 5cm x 4cm.
What is 3 g/cm3?
Ability to burn is an example of this.
What is chemical property?
Heated water forms bubbles of water vapor inside it.
What is boiling?
This occurs only on the surface of a liquid.
What is evaporation?
It's the bottom number, below the atomic symbol.
What is atomic mass?
***DAILY DOUBLE***
The density of 28g of iron that was added to a graduated cylinder containing 40ml of water, causing the water level to rise to 44ml.
What is 7g/ml?
Compared with those of a liquid, the molecules of this matter are farther apart from each other.
What is gas?
An egg being fried in a pan is an example of this.
What is chemical change?
Changing the number of neutrons of an element creates this.
What is an isotope?
This is the calculation to determine the number of neutrons in an element.
What is round the atomic mass to the nearest whole number, then subtract atomic number from atomic mass.
Adding a 6g/ml object to water will cause the object to do this.
What is sink?
The four main phases of matter.
What are solid, liquid, gas, and plasma.
Sugar dissolving in warm water is an example of this.
What is physical change?
(TRUE OR FALSE)
If you have the same volume of two different substances, they may have different densities.
What is true?
