CHAPTER 16 WHAT IS MATTER?
SECTION 16.2 Measuring Matter A review on measuring the volume and mass of matter.
Liquid volume measurements: Easy to do… simply pour liquid into a marked container… …and read the volume mark.
To get the greatest accuracy, keep two things in mind: First, read the mark at eye level.
Second, read the volume at the bottom of the meniscus, (the curve in the surface of the liquid) if the curve is downward.
If the meniscus curves upward, then read it at the top of the curve.
Solid volume measurements: So, whats a regular solid? Calculate the volume of regular solids by using a formula.
Check out page 272 in your IPC textbook:
Use the displacement method to find the volume of an object with an irregular shape.
Submerge the object in water and measure how much water the object displaces or pushes aside.
Lets measure the volume of a small object like a key… Step 1: Fill a 100 ml graduated cylinder with water to the halfway point – 50 ml.
Step 2: Gently slide the key into the water. The water level in the graduated cylinder will rise as the key displaces some of the water.
Step 3: Take a new volume reading. The difference in the two volume readings is the volume of the key. (53 ml – 50 ml = 3 ml)
Mass is the amount of matter in an object. Mass is measured on a balance. Mass is measured in units of grams (g).
A balance measures the mass of an object by comparing it to objects whose masses are known.
Mass is independent of the force of gravity. Would a balance function correctly on the moon? Why or why not?
A scale measures the gravitational force (weight) between an object and Earth. Would a scale function correctly on the moon? Why or why not?
How do you measure quantities of matter that are very small or very large?
We can use indirect measurement: Obtain a sample of the matter that is a measurable size. Measure its volume and mass.
Estimate or measure either the mass or the volume of the matter. Set up a proportion. Example: mass of sample = mass of matter volume of sample volume of matter
Solve for the unknown quantity. mass of matter = mass of sample x volume of matter volume of sample
Density A Characteristic Property of Matter. Density Density is a basic characteristic property of all matter A characteristic property is a property.
Metric System Scientific Measurements- Review. Metric System Developed by the French in the late 1700’s. Based on powers of ten, so it is very easy.
Mass is the amount of matter (stuff) in an object. What is mass? The base unit of mass in the metric system is the gram (g).
What is Matter? Chapter 2 Section 1. Matter What do all of these objects have in common? These objects all have volume and mass. Matter - is anything.
Metric System Scientific Measurements. Metric Prefixes Regardless of the unit, the entire metric system uses the same prefixes. Regardless of the unit,
Proper Lab Technique. Measuring a Liquid Volume When a liquid is placed in a piece of laboratory equipment such as a graduated cylinder, buret, or a beaker,
DENSITY. KEY QUESTIONS What is density? How is density measured? How do you calculate density?
DENSITY. What Is Density? Density is how heavy something is for its size. Density is mass divided by volume or D=m/v D = density, M = mass V = volume.
Using Metric Tools. 1. Ruler The ruler above has an English side that uses inches and a metric side that uses centimeters. We will only use the metric.
The Properties of Matter What is matter?. Matter Everything is made of MATTER! Matter is anything that has volume and mass. Volume is the amount of space.
MEASUREMENT. SI UNITS These are the units that scientists use when they are measuring things. We will use them in this class Youve heard of them before.
Title: Measuring Volume Activity 8. Read A-32 Problem: How do you measure volume of a solid object? Hypothesis/Initial Thoughts:
Warm –up: What is the density of the block? CUBE DESCRIPTION Material Plastic Length of each side 2 cm Mass 24 grams Weight 6.6 N.
The Properties of Matter Chapter 2. Problem Solving Scientists will often use an object’s properties to best help them solve a problem.
Chap 1 Section 2- Describing Matter Characteristics of matter The SI system – units of measurement Conversion of the units and calculation Identify physical.
Density How compact is the material?. How close the atoms or molecules are to each other More than“heaviness”- density includes how much space an object.
WHAT IS MATTER?. Matter What Is Matter? Matter is anything that has mass and takes up space. Matter in the Universe Everything in the universe that you.
Mass vs Weight Whats the Difference?. Mass Mass is a measure of how much matter is in an object. Do you remember what matter is? Stuff.
The Metric System The scientific system of measurement The International System of Units (SI) Based on the number 10 and multiples of 10.
Introduction to the Metric System ACS Ms. Grogan.
States of Matter. What three things are made of matter? Solids, liquids, gases.
Which do you think would have the greater volume and mass? Why? 1 kg of feathers1 kg of rock.
Density is… the amount of matter in a given area. Ex. population density (Alaska has 1 person/mi 2, New Jersey has 1174 person/mi 2 )
Making Measurements in Science The standard system of measurement all scientists use is the METRIC SYSTEM.
How are Mass and Weight Different?? What is Gravity? A force of attraction between objects due to their masses. This attraction causes objects to.
Matter and Energy Chapter Vocab Matter – anything that has mass and takes up space Mass – measure of how much matter an object has.
Academic Chemistry BB density lab. Objectives Calculate density of BB’s Measure volume using the water displacement method Determine if a BB is solid.
Year 10 Pathway C Mr. D. Patterson 1. Refer to weight as a force Use F=ma to calculate weight on Earth and other planetary bodies 2.
Scientific Measurement Using Laboratory Equipment and The Metric System.
Gravity Unit F, Chapter 1, Section 1 pF6-11. Forces Make Things Move Force: push or pull – Act of objects – Often affect motion of objects Cause objects.
