Skill Test 2

Celcius to Farenheit

Tc = (Tf—32)/1.8

Farenheit to Celcius

Tf = 1.8 Tc + 32

Kelvin to Celcius

Tc + 273.15

The volume raises?

Subtract

Density formula

D = mass/volume

Volume formula

V = mass/density

Mass formula

m = density x volume

Mass of chemical

Mass of container with chemical -- mass of empty container

Cubic volume formula

V = lwh

Cylinder volume formula

V = πr²h

Insoluble

Not dissolvable in water

Soluble

Dissolve in water

If it sinks, the substance is

denser

ΔP

760 mmHg — atmospheric pressure (in mmHg)

CNBP

observed boiling point + (0.05 x ΔP)

Temperature above the boiling point

exists in gaseous state

Below the melting point

exist in solid state

Qₑₓₚ

variance/range

If Qₑₓₚ was greater?

Reject outlier

If Qₑₓₚ was lesser?

Do not reject “outlier”

Highest value varince

highest value — next highest value

Lowest value

lowest value — next lowest value

Range

highest value — lowest value

Average

sum of all x /number of trials

AAD (Average absolute deviation)

sum of all individual deviations / number of trials

Absolute individual deviation

| individual value — average value |

ppt (parts per thousand)

(AAD/average value) x 100

Final Result

average value ± AAD

percent error

((|Experimental value - Accepted value|) /Accepted Value) x 100
