Definitions; Mix and flow of matter

Question 1

What is a fluid?

Answer 1

Matter that has no definite shape, can flow and takes the shape of its container: substance in gas or liquid state

Question 2

What is a Pure substance?

Answer 2

Substance that is made up of only one type of particle throughout

Question 3

what is a mixture?

Answer 3

Made up of two or more pure substances

Question 4

Whats a heterogenous mixture? (HE)

Answer 4

A mixture where you can see the different substances due to the particles staying together but not intermingled.

Question 5

What is a homogenous mixture?

Answer 5

A mixture that is made up of different substances, and they can’t be seen because the particles are intermingled.

Question 6

what is a solution?

Answer 6

AKA homogenous mixture; different substances can’t be seen because the particles are mixed.

Question 7

What is a mechanical Mixture?

Answer 7

AKA heterogenous mixture; the different substances can be seen because the particles stay together but aren’t mixed.

Question 8

what is a solute?

Answer 8

substance that gets dissolved in a solvent to form a solution

Question 9

What is a solvent?

Answer 9

Substance that dissolves a solute

Question 10

What is concentration?

Answer 10

amount of solute (g/kg) that gets dissolved in a specific amount of solvent (mL/L) in a solution (g/mL)(kg/L)

Question 11

What is a saturated solution?

Answer 11

A solution where no more solute can be added/dissolved at a given temp

Question 12

What is an unsaturated solution?

Answer 12

Solution where more solute can be dissolved at a given temp

Question 13

What is solubility?

Answer 13

ability to dissolve; mass of solute that can dissolve to form a saturated solution

Question 14

What is a saturation point?

Answer 14

The point where no more solute can be added in a given volume of solvent at a given temp

Question 15

What is an aqueous solution?

Answer 15

water is the main solvent

Question 16

what is viscosity?

Answer 16

the internal resistance/friction that keeps a fluid from flowing

Question 17

what is density?

Answer 17

mass per unit volume; it can be found by dividing mass by volume

Question 18

what is the buoyant force?

Answer 18

the upwards force that a fluid exerts onto an object; opposite of what gravity in a fluid does in an object

Question 19

what is buoyancy?

Answer 19

the tendancy of an object to float when placed in a fluid

Question 20

what are elements

Answer 20

can’t be broken down

Question 21

what are compounds?

Answer 21

two or more elements

Question 22

IMPORTANT: what is colloid?

Answer 22

an HE mixture in which the particles don’t settle, and stay mixed together

Question 23

IMPORTANT: what is emulsion?

Answer 23

when droplets of fat are prevented from joining by an emulsifying agent

Question 24

IMPORTANT: what is suspension?

Answer 24

an HE mixture in which the particles don’t settle, but eventually seperate from one another

Question 25

What is mass?

Answer 25

amount of matter in an object

Question 26

what is volume?

Answer 26

amount of space occupied by a 3D object
