Science - Chemistry/ Characteristic properties of substances

Question 1

True/False: Intensive Properties depend on the amount of matter or quantity

Answer 1

False: they do not depend on the amount of matter, it will not change if more or less is there

Question 2

Answer 2

Depend on the matter or quantity of sample

Question 3

Mass

Answer 3

measure of amount of substance in an object

Question 4

weight

Answer 4

measure of gravitational pull of earth on an object

Question 5

volume

Answer 5

measure of amount of space occupied

Question 6

density

Answer 6

measure of amount of mass per unit volume

Question 7

what is the formula for density

Answer 7

D = M/V

Question 8

Conduction

Answer 8

form of heat transfer that requires energy

Question 9

True/False: Conduction requires energy for it to occur

Answer 9

TRUE

Question 10

where does heat go

Answer 10

from an area of high concentration to low concentration

Question 11

Thermal Equilibrium

Answer 11

2 regions are equal temperature// No heat transfer

Question 12

What are the properties of Water

Answer 12

High Polarity, Hydrogen Bonding, cohesiveness, Adhessiveness, Solvent

Question 13

Solvent

Answer 13

other substances dissolve in it

Question 14

cohesiveness

Answer 14

attracted to itself

Question 15

adhesiveness

Answer 15

attracts other molecules

Question 16

Osmosis

Answer 16

diffusion of water through a semi-permeable membrane from an area of high concentration to an area of low concentration

Question 17

State of Matter: Solid (Volume.Shape) (Density) (Compressibility) (molecular motion)

Answer 17

(Volume/shape: Definite) (Density: High) (Compressibility: none) (Molecular motion: vibrate @ fixed position)

Question 18

State of Matter: Liquid (Volume/shape) (Density) (Compressibility) (Molecular motion)

Answer 18

(Volume/ shape: Volume = constant// Shape = assume shape of container) (Density: High) (Compressibility: none) (Molecular Motion: move past each other freely)

Question 19

State of Matter: Gas (Volume/shape) (Density) (Compressibility) (Molecular Motion)

Answer 19

(Volume/shape: Volume = assume volume/shape of container) (Density: Low) (Compressibility: High) (Molecular Motion: Very free)
