Q

What is the definition of heat of vaporization

A

The amount of heat needed to convert a unit mass of a substance from its liquid phase to its vapor phase at constant temperature

17
Q

What are the major ideas of kinetic molecular theory

A
  • Gases contain particles
  • gas particles collide with each other and with the loss of the container these collisions may result in a transfer of energy but no net loss of energy as result of these collisions
  • gas particles are separated by relatively great distances
  • gas particles do not attract each other
18
Q

What is the relationship between pressure and number of gas particles

A

The greater the number of air particles the greater the pressure

19
Q

What is the relationship between pressure and volume of a gas

A

If one of the variables increases the other must decrease

20
Q

What is the relationship between pressure and temperature

KE=(1/2)mv^2

A

An increase in temperature causes the pressure to increase

21
Q

What is the relationship between temperature and volume

A

Temperature and volume are directly related

22
Q

What is the relationship between temperature and velocity

A

The higher the temperature the greater the average velocity of the particles

23
Q

What is the equation for combined gas law

A

(P1 x V1)/ T1 = (P2 x V2)/ T2

24
Q

What are the ideas of the kinetic molecular theory

A
  • Gas particles do not attract one another
  • gas particles do not occupy volume
  • gases are most ideal at low pressures and high temperatures
25
Q

What is one mole called

A

Avogadro’s number

26
Q

What is the definition of immiscible

A

To liquids that are not soluble in each other

27
Q

What is the definition of miscible liquids and how can they be separated

A

They are liquids that can mix with each other and they are separated by the process of distillation due to having different boiling points

28
Q

How are substances’s separated in the process of chromatography

A

Components of the mixture move a different rates as they begin to separate from each other as they move the paper

29
Q

Are the properties of a solid?

A

Definite volume and shape
