CHARLESLAW

1.    DEFINE

TEMPERATURE: the measurement of theamount of energy in something

·     If we lessen the kinetic energy (you cool itdown)

·     If you add energy (the temperature will rise)

PRESSURE

·     Force applied per unit area

BAROMETER

·     Used to measure air pressure (AtmosphericPressure)

MANOMETER

·     Measures a gas in a fixed container (volume)

PASCAL

ATMOSPHERE

DALTONS LAW OF PARTIAL PRESSURE

The two largest influences on gasesare temperature and pressure.

2.    What two factors determine the kinetic energy ofa particle? TEMPERATURE AND PRESSURE

How do we calculate the kineticenergy in a particle?

3.    What is the SI unit for temperature?

4.    What is the average air pressure at sea level?

What is the SI unit for pressure?

What is it equal to?

What is one atmosphere equal to inthe following units: mmHg, torr, Kpa, psi, bar, inHg

STANDARD PRESSURE: They are allequal to each other, to one atmosphere

o  29.92 inHg

o  1 atm (Atmosphere)

o  101.3 KPa (used mostly in European region)

o  101300 Pa*

o  760 mmHg

o  760 torr

o  14.7 psi

o  1012.9 mbar

o  1.0129 bar

BOYLES LAW

1.     What does Boyle’s Law state?

Deals with pressure with a closed space, itsays that they are inversely proportional (One goes up, the other goes down)Pressure and Volume

What two things must remain constant?

Temperature and amount of the gas

THE TEMPERATURE MUST BE IN KELVINDegree C + 272

2.     Howdo we describe the relationship between pressure and volume?

They are inversely proportional (as onerises, the other one decreases)

According to Boyle’s Law what happens to thevolume of a gas as the pressure rises?

It decreases

3.    What equation do we use to show Boyle’s law?

Practice Problems Page 443 # 1 and 2

            P₁x V₁ = P₂ x V₂

4.    What does Charles’s law state?

Shows the relationship between volume and temperature,they are directly proportional, as one goes up, the other goes up.

What two things must remain constant?

Pressure and Number of particles

Describe the relationship between thetemperature and the volume of a gas.

They are directly proportional, as one goesup, the other goes up (

5.    Give the equation to calculate Charles’sLaw.

What temperature scale must be used tocalculate Charles’s Law?

6.    Practice Problems page 446, # 4, 5, 6

GAY LASSACS LAW

1.    What does Gay-Lassac’s Law state? What mustremain constant?

2.    How does Gay-Lassac’s Law describe therelationship between pressure and temperature?

Are proportionally as pressure goesup, temperature will go up.

3.    What equation is used to show Gay-Lassac’s Law?

P₁ = P₂

T₁    T₂

4.    Practice Problems page: 448 # 8,9, and 10

YOU MUST USE KELVIN TEMPERATURE

THE PRESSURE UNITS MUST BE THE SAME
