Mod 3 Lesson 3

Question 1

Absolute pressure

Answer 1

equal to gauge pressure plus atmospheric pressure

Question 2

Amonton’s law

Answer 2

(or Gay-Lussac’s law) at a constant volume and number of molecules, the pressure is proportional to the temperature

Question 3

Boyle’s law

Answer 3

at a constant temperature and number of molecules, the absolute pressure of a gas and its volume are inversely proportional

Question 4

Charles’s law

Answer 4

at a constant pressure and number of molecules, the volume of a gas is proportional to its absolute temperature

Question 5

Combined gas law

Answer 5

combines Boyle’s law, Charles’s law, and Amonton’s law to get the law which has no official founder and can be written as PV/T1=PV/T2

Question 6

Gas pressure

Answer 6

caused by the force exerted by gas molecules colliding with the walls of the container

Question 7

Ideal gas

Answer 7

a hypothetical construct that real gases approximate under certain conditions

Question 8

Ideal gas law

Answer 8

describes the behaviors of real gas in the limitations of low density and high temperature

Question 9

Kinetic molecular theory (KMT)

Answer 9

describes the microscopic properties of atoms (or molecules) and their interactions, leading to observable macroscopic properties such as temperature, volume, and pressure

Question 10

Manometer

Answer 10

a device that can be used to measure the pressure of a gas trapped in a container

Question 11

Pressure

Answer 11

the force exerted on a given area; the formula for pressure is: P=FA

Question 12

Real gas

Answer 12

behaves more or less like ideal gas except at high pressures and low temperatures
