Gas Laws

Learning Target 3.2.1: I can convert between various units of pressure, temperature, and volume.

Goals

3.2.1.a I can explain how pressure and temperature are related to the Kinetic Molecular Theory

3.2.1.b I understand what pressure is and I can convert between different units of pressure.

3.2.1.c I understand what temperature is and I can convert between different units of temperature.

3.2.1.d I understand what volume is and I can convert between different units of volume.

Learning Target 3.2.2: I can explain the relationships between volume of a gas, its temperature and its pressure using Boyle’s Law, Charles’s Law, Gay-Lussac’s Law, and the Combined Gas Law and how changing one variable affects the others.

Goals

3.2.2.a I can identify a graph of two variables as directly proportional or inversely proportional.

3.2.2.b I can demonstrate that under constant temperature, if you increase the pressure you will decrease the volume.

3.2.2.c I can calculate the change in volume or pressure of a gas in a closed system if I know the change in pressure or volume at a constant temperature using

P1V1 = P2V2 (Boyle’s Law)

3.2.2.d I can demonstrate that under constant pressure, if you increase the temperature you will increase the volume.

3.2.2.e I can calculate the change in volume or temperature of a gas in a closed system if I know the change in temperature or volume at a constant pressure using V1/T1 = V2/T2 (Charles’s Law)

3.2.2.f I can calculate the change in volume or pressure of a gas in a closed system if I know the change in pressure or temperature at a constant volume using P1/T1 = P2/T2 (Gay-Lussac’s Law)

3.2.2.f I can calculate the change in volume or pressure of a gas in a closed system if I know the change in pressure or temperature at a constant volume using P1/T1 = P2/T2 (Gay-Lussac’s Law)

Goal 3.2.2.h I can calculate the change in volume or number of moles of a gas in a closed system if I know the change in volume or number of moles at a constant temperature and pressure using V1/n1 = V2/n2 (Avogadro’s Law)

Learning Target 3.2.3: I can explain the Ideal Gas Law and how it relates to kinetic molecular theory.

Goals

3.2.3.a I can describe how the Kinetic Molecular Theory relates to an Ideal Gas.

3.2.3.b I can identify the units of Standard Temperature and Pressure that will be used in calculations.

3.2.3.c I can calculate one unknown from PV=nRT if I know the other three variable values.
