Tomorrow’s Quiz4 – CN: Direct vs.

Indirect Variation5 – Work Time

Today’s Goal:Students will be able to

contrast direct and inverse relationships between variables.

Homework1. STUDY for tomorrow’s

QUIZ2. Tomorrow is the last

day for Calculator Check-in for a Grade

REVIEW

Answer: Dalton’s Law of Partial Pressures says that the total pressure is equal to the sum of the individual pressures.Ptotal = Pgas 1 + Pgas 2 + Pgas 3 + … + Pgas n

What’s on Tomorrow’s Quiz

Everything from the past week and a half: From Section 10.1 and notes:

Moles and Mole-Particle Conversions From Section 12.1 and notes:

Kinetic Molecular Theory Boyle’s Law & calculations Dalton’s Law of Partial Pressures &

calculations Direct vs. Inverse Relationships

You will be given the necessary equations, but you will need to know how to use them with correct UNITS

Cornell Notes

Topic: Direct and Inverse Variation

Date: 2/6/2014Name:Period:

(Include your Name and Period in case you lose your notes, so that I can return them to you through the Lost and Found bin)

Direct Variation

y varies directly with x (or: "x and y are directly proportional") if there is a constant k such that:

y = kx x and y are on opposite sides of the

equal sign, but they are on the same “level” of the fraction (y = x)

“as x increases, y increases” or “as x decreases, y decreases”

Inverse Variation

y varies inversely with x (or: "x and y are inversely proportional") if there is a constant k such that:

y = k/x x and y are on opposite sides of the

equal sign, but they are on different “levels” of the fraction

(y = 1/x)

“as x increases, y decreases” or “as x decreases, y increases”
