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
