Properties of substances

Question 1

Intensive physical properties

Answer 1

Physical properties that do not change by the substance’s size. Boiling point, melting point, luster, conductivity, malleability, density, specific heat

Question 2

Specific heat capacity

Answer 2

The amount of energy needed to change the temp of 1 gram of a substance by 1 degree celcius

Question 3

Extensive properties

Answer 3

Characteristics that change with sample size. length, volume, mass, energy, enthalpy, entropy

Question 4

Polar covalent bond

Answer 4

Electrons are NOT equally shared between molecules, creates a negative and positive spot on the molecule

Question 5

Hydrogen bond

Answer 5

A type of non-covalent bond between the partial negative region of an O molecule and a partial positive of a hydrogen, creating surface tension

Question 6

Non-polar covalent bond

Answer 6

Electrons are shared evenly between molecules

Question 7

Diffusion

Answer 7

the passive movement of a substance from areas of high concentration to low

Question 8

Osmosis

Answer 8

The diffusion of water through semi permeable membranes down a concentration gradient
