Chapter 5: Gases, Liquids + Solids

Question 1

What is Boyle’s Law of a pressure-volume relationship?

Answer 1

if the pressure increases; then the volume decreases proportionally.
P1V1= P2V2

Question 2

What is Charles’ Law of a temperature- volume relationship?

Answer 2

temperature and volume are directly proportional to one another.
V1/T1= V2/T2

Question 3

What is the combined gas law?

Answer 3

P1V1/T1= P2V2/ T2

Question 4

What is the ideal gas law and what does n and R stand for?

Answer 4

PV= nRT
n= number of moles of gas
R= ideal gas constant which is almost always 0.0821

Question 5

What is Dalton’s Law of partial pressure?

Answer 5

P(total)= P1+P2+P3+…….

Question 6

What is the relationship of boiling water at or above sea level?

Answer 6

As the atmospheric pressure increases, so does the boiling point. The atmospheric pressure increases the lower the feet above sea level is.

Question 7

What are Dipole-Dipole interactions?

Answer 7

this happens when opposite charges attract and move together

Question 8

What are London Forces?

Answer 8

temporary attractive force that results when electrons from adjacent atoms form temporary and weak dipole interactions

Question 9

What are Hydrogen Bonds?

Answer 9

extra strong dipole-dipole interactions that include O, F, or N with at least 1 lone pair with a hydrogen attached to it.
