States Of Matter

Question 1

List the three states of matter

Answer 1

•solid
•liquid
•gas

Question 2

List the four gas laws

Answer 2

•Boyle’s law
•Gay Lusac’s law
•Charles Law
•Avogadros law

Question 3

Describe Boyle’s law

Answer 3

This law states that when temperature is held constant,pressure and volume are inversely proportional

Question 4

State Charles Law

Answer 4

This law states that when pressure is held to constant temperature and volume are directly proportional.

Question 5

State Gay Lusac’s law

Answer 5

States that when volume is constant pressure and temperature are directly proportional.

Question 6

State Avogadro’s gas law

Answer 6

This law states that when pressure and temperature are held constant the number of moles is directly proportional to the volume of a gas.

Question 7

What is the Ideal Gas Equation?

Answer 7

PV=nRT

Question 8

Define triple point

Answer 8

This is when a substance has its solid,liquid and gas phases in equilibrium at a given pressure and temperature

Question 9

Define critical point

Answer 9

This is when the liquid and gas phases are indistinguishable

Question 10

Define normal boiling point

Answer 10

This refers to the temperature and pressure where a liquid changes to a gas at 1 a.t.p

Question 11

Define normal melting point

Answer 11

This refers to the temperature and pressure where a solid changes to a liquid at 1 a.t.p

Question 12

During phase changes,what is the energy used for?

Answer 12

Energy is used to break bonds and not to increase kinetic energy therefore temperature does not change

Question 13

What are phase diagrams used for?

Answer 13

Used to depict the behavior of matter based on pressure and temperature

Question 14

What are heating and cooling curves used for?

Answer 14

Used to depict the changes of state based on heat and temperature
