Flashcards in Exam I formulas Deck (12):

1

## Charles' Law

###
V/T (initial) V/T (after)

-as temperature increases, volume increases

-direct relationship (linear graph)

2

## Boyle's Law

###
PV (initial) = PV (after)

-as volume decreases, pressure increases

-inverse relationship (curve)

3

##
Avogadro's Law

###
V/n (initial) = V/n (after)

-as volume increases, moles increase

-direct relationship (linear graph)

4

## Ideal Gas Law

### PV = nRT

5

## Density

###
p = (MW * P)/(RT)

number density: p = n/V

mass density: p = m/V

6

## molecular weight

### MW = (pRT)/P

7

## Kinetic energy

### E(k) = (3/2)RT = (1/2)mv^2

8

## Vrms

### v(rms) = sqrt (3RT/M)

9

## Gay-Lusaac's Law

###
P/T (before) = P/T (after)

direct relationship

10

## Difficult to do this law

### nT = nT

11

## comparing velocities at the same temp

### v1/v2 = sqrt M2/M1
