Exam Experience Part 1-12/19/12-Dani Swords

unit of measurement

cm³ - centimeters cubed (volume)

g - grams (mass)

Volume

Lenght x Width x Height = Volume


Volume Displacement method: put water into a graduated cylinder. record the measurement. place object inside the graduated cylinder. record the new measurement. original-new=volume

Ruler

Measure from the zero

Mass

use the balance

check if the pan is the correct one

clean the pan

zero the balance

mass the object

Change in mass

Mf (mass final)

-Mi (mass initial)

ΔM (change in mass)

Density

m=D

v

mass =Density

volume

Lab 1.4 (Sand)

Volume of sand alone=(sand+water)-water

Volume of air space= dry sand-sand alone

Fraction of sand that is air= airspace over dry sand

Percent of sand that is air= (airspace over dry sand) times 100

Sensitivity

ΔM = Sensitivity

# of yes'

Volume of a Gas in a otherwise empty room

(L x 100 x W x 100 x H x 100)


D=m
