Question 1

gases are characterized with their

Answer 1

pressure = force/ area

Question 2

extensive property of matter

Answer 2

depends on the amount of the substance

Question 3

intensive properties

Answer 3

do not depend on the amount

ex. density

temperature

pressure

Question 4

unit of pressure

Answer 4

1 pascal(Pa) = 1N/m²

1 atm = 760 mmHg = 760 torr

1 atm = 101,325 Pa

1 atm= 101.3 KPa

Question 5

gases unlike solids and liquids

Answer 5

obey the same laws

they must fulfil certain requirments

Question 6

elastical ellisions

Answer 6

do not lose heat, complete transfer, no friction between gases!

Question 7

perfect motion for ideal gases

Answer 7

high temp, low pressure

gas particles are far from each other

Question 8

moler volume of ideal gases

Answer 8

22.4 L

Question 9

partial pressure

Answer 9

pressure of a gas in a mixture of different gases is the pressure that th gas would exert alone in the container

Question 10

london forces

Answer 10

only force for non polar molecules weak

Question 11

wich can be more distorted small or large molecules

Answer 11

large because the van der waal forcesa re sronger in bigger molecules

Question 12

hydrocarbons

Answer 12

organic molecules that only contain carbon and hydrogen

Question 13

Question 14

hydrogen bonding

Answer 14

attached to electronegitive O,F,N

Question 15

the stronger themolecular force

Answer 15

the stronger the surface tention

Question 16

evaporation

Answer 16

when they overcome the molecular forces until all liquid is gone
