What is the formula for Density?
D = M/V
100
What is the formula for mass?
M = D x V
100
Define volume
THe amount of space that an object has
100
What is official name of the metric system?
It is the International System of Units.
100
Fill in the blanks: Comparing the density of an object to the density of water can tell you whether the object will _______ or _______
sink, float
200
All scientist use the metric system but should measurements be accurate and why?
Measurements should be accurate so that information can be easily communicated.
200
What is mass?
It's the amount of matter in an object.
200
How is the volume of a rectangular prism calculated?
Width x Length x Height
200
What is matter?
Matter is anything has mass and volume. Everything that you can touch, feel, see and taste
200
How is density related to the ability of an object to float?
If the density of an object exceeds (is bigger than) the density of water, it will sink. If the object has a density that is less than the density of water, it will float.
300
What is the density of an object with a mass of 45g and a volume of 8cm3
5.625 g/cm3
300
What tool is used to find mass and what is the measurement unit?
Triple Beam Balance and it is measured in grams or kilograms
300
How are 1 mL and 1 cm3 related?
They are both measurements of volume
300
Define what gravity is.
Gravity is the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
300
Name all of the units for density (volume, mass, density)
Volume = mL or cm3 Mass = g, kg Density = g/mL or g/cm3
400
What will happen if you drop an object into water that has a density of 1.33g/cm3?
It will sink
400
What does the term ZEST mean?
Zero out the balance Estimate the mass Slide the riders Total out the mass
400
Tools used to measure volume
Graduated Cylinder, Beaker and Flask
400
Explain what buoyancy is.
The tendency of an object to float
400
How do you covert metric units?
Big to small multiply and move the decimal to the right. Small to big divide and move the decimal to the left.
500
Name the 3 states of matter from highest to lowest density
Solid = the highest density Liquid = "medium" density Gas = the least density
500
Name the basic metric units of Distance, Volume, Mass, Time and Temperature.
Distance - Meter Volume - Liter Time - Second Temperature - Degree (Celsius)
500
Explain the displacement method of finding the volume of an object.
When an object is irregular, you can find the volume using displacement. This is done by putting water in a graduated cylinder and recording the volume. Drop the object in the water and record the changed volume. Subtract the original volume from the final volume to determine the volume of the the object.
500
What does "standardize" mean?
To evaluate by comparing to a standard
