Measuring Matter Chapter 2 Section 2

1/6 of what you weigh on Earth! Weight Weight is a measure of the force of gravity on an object. Would your weight be the same if you were on the moon? You would weigh about 1/6 of what you weigh on Earth!

MASS Measurement of the amount of matter in an object. Does your mass change on the moon? A physical property

1,000 Units of Mass International Systems of Unit “SI” SI unit of mass is the KILOGRAM. How many grams are in a kilogram? 1,000

What is my mass? = 150 grams = 5 grams

Volume The amount of space that matter occupies. Liquids, Solids, & Gases have volume.

Units of Volume 1 Liter bottle = 1,000 milliliters 1 milliliter = liter (L) milliliter (mL) cubic centimeter (cm³) 1 Liter bottle = 1,000 milliliters 1 milliliter = 1 cubic centimeter

What is my volume? = 4.92892159 milliliters = 355 milliliters

Calculating Volume Volumes of solids are usually expressed in cubic centimeters Volume = Length x width x height Don’t forget to label the units! How do you measure the volume of an irregular object? If a penny makes the water go up 4 milliliters, what is its volume? 4 cubic centimeters Water level rise = Volume of object in milliliters

Density Density relates the mass of a material in a given volume. NO! Two materials have the same volume, do they have to have the same mass? Density Density relates the mass of a material in a given volume. NO! A kilogram of sand takes up much less space than a kilogram of feathers! # of grams in one cubic centimeter The volumes differ because they have different densities.

every gram of water has a volume of 1 cm³ Water at room temperature = Density of Water 1g/cm³ This means: every gram of water has a volume of 1 cm³ Mass Volume Density =
