What is a compound?
Substance in which the atoms of 2 or more elements are combined in a fixed proportion.
What is a physical change?
Physical change is a change in size, shape, or state or matter.
What is thermal expansion?
The increase in the volume of a substance when the temperature is increased.
How is atomic mass calculated?
According to their natural abundances.
What is a noble gas?
