in which state of matter is kinetic energy the greatest?

measurement of movement

why does the mass stay the same in a closed system when matter changes state?

all mass gets trapped inside. nothing else leaves.

why can the mass of an open system change?

because the system changed. gas can escape mass changes.

properties are...

characteristics that help us identify different types of matter.

dissolve

breaking apart into pieces so small you can't see them

substances

different types of matter like table salt or sugar

density

the mass of an object divided by the volume or space it takes up

solubility

the ability to dissolve

flammability helps to determine what gas was produced;

the flame went out because it is nonflammable.

because the gas is less dense, it will...

rise

because the gas is MORE dense, it will...

sink

sample equation that illustrates LOCOM (Law of Conservation of Mass)

12 grams input + 10 grams input Y = 2 grams output
