20
Q

a combination of two or more substances in which the original substances are separated into physical distinct regions.

A

heterogeneous mixture

21
Q

a combination of two or more substances that have uniform composition and chemical properties throughout; also known as a solution.

A

homogeneous mixture

22
Q

any force that can hold or repel particles.

A

intermolecular force

23
Q

how readily a material’s shape can be changed.

A

malleability

24
Q

anything that has mass and takes up space.

A

matter

25
Q

when a solid turns into a liquid.

A

melting

26
Q

the temperature at which a solid turns into a liquid.

A

melting point

27
Q

a special type of physical change in which a substance transitions among the states of matter, solid, liquid, and gas, but the chemical properties of the substance remain the same.

A

mixture - phase change

28
Q

a change which alters a substance without altering its composition.

A

physical change

29
Q

a characteristic that can be observed or measured without changing the chemical makeup of a substance. Types include color, odor, texture, boiling point, melting point, and density.

A

physical property

30
Q

the relative ability of a substance to undergo a chemical reaction.

A

reactivity

31
Q

a combination of two or more substances that have uniform composition and chemical properties throughout; also known as a homogeneous mixture.

A

solution

32
Q

when a solid transistions into a gas without going through the liquid phase.

A

sublimation

33
Q

a measure of the random kinetic energy in a sample of matter.

A

temperature

34
Q

the phase change from liquid to gas.

A

vaporization

35
Q

how closely packed together the atoms are - if density is .99 or less then it’s too light and it floats - if density is greater than 1 then it’s too heavy and it sinks

A

buoyancy

36
Q

A measure of how easily something snaps back to it’s original shape after it has been stretched or squeezed.

A

Elasticity

37
Q

a single kind of substance- has only one kind of atom in it - it Cannot Be Broken Down into a simpler substance - it has one name and only one chemical symbol that represents it, like Carbon. Carbon’s symbol is C. Gold is Au. So it’s an element

A

Element

38
Q

how “hard” it is to scratch something - “hard to scratch” - the “hardest” mineral is a diamond - diamond can scratch everything else because it’s so hard.

A

Hardness

39
Q

different or “not the same”

A

Hetero

40
Q

the same

A

Homo

41
Q

how much space something occupies or takes up

A

mass

42
Q

solid, liquid, gas, plasma (lowest temperature ( energy) to highest temperature (energy)

A

States of matter

43
Q

how strong a solid is in resisting being pulled apart. Remember the sheet of paper?

A

Tensile strength

44
Q

how slow a liquid pours - how thick it is- the viscosity of syrup is higher than than water because it is thicker and pours slower - you heat syrup and it becomes easier to pour(it is thinner and its viscosity number has dropped)

A

Viscosity

45
Q

how much matter is in something

A

volume
