A type of matter can change physically while remaining the same type of matter.
Formation of gas, change in color, change in odor, change in temperature, emission of light, formation of a precipitate
identical
Explain how evidence can be used to describe matter.
observations or quantitative measurements of physical properties of matter can be used as evidence to describe types of matter.
What is an example of evidence that can be used to explain that matter is made of particles too small to be seen?
Inflating a balloon, evaporating liquids, dissolving a substance
How can you prove that the total weight of matter is conserved during a physical change?
Measure the matter before and after the change occurs.
What kind of evidence of a chemical change would you expect to find when you burn a match?
Change in temperature or emission of light.
Describe a molecule.
Molecules form when atoms join together with other atoms.
