Measurements
What is the density of water?
1.0g/mL
What is the formula for density?
Density = Mass / Volume
What is the definition of density?
The measurement of how much mass of a substance is contained in a given volume.
How can we measurement the volume of an irregularly shaped object (like a rock)?
Displacement in water
What is the density of an object that sinks in water?
Greater than 1.0g/mL
What is the formula for volume?
Volume = Mass / Density
What is the definition of volume?
The amount of space that a substance/object takes up.
When measuring the Volume of a solid object, what unit is it usually expressed in?
In cubic centimeters or meters.
What is the density of an object the floats in water?
Less than 1.0g/mL
What is the formula for mass?
Mass = Density X Volume
What is the definition of Mass?
The measurement of the amount of matter in an object.
Why does ice float in water?
How does density relate the the Metric System of Units?
Density uses units such as grams and kilograms for mass and m3, cm3, and milliliters for volume.
