Sink or Float?
What does this density represent 1.0g/mL ?
Density of water
What is the definition of Density?
The measurement of the amount of matter (mass) in a substance compared to the amount of space (volume) the substance occupies.
4.67g / 32.8mL. Find Density and say if it sinks or floats.
0.14g/mL. The object floats.
How can you decrease or make something less dense?
Increase the volume
An object with a density greater than 1.0g/mL will do what in water?
Greater density then water means the object will SINK in the water.
L x W x H is the formula for...
Volume of a regular shaped object
What is the definition of Volume?
The amount of space an object takes up.
Density = 1.74g/mL
Volume = 63mL.
Find the mass.
109.62g
When measuring the Volume of a solid object, what unit is it usually expressed in?
In cubic centimeters or cm3
An object with a density less than 1.0g/mL will do what in water?
Greater density than water means the object will FLOAT in the water.
What is the definition of Mass?
The measurement of the amount of matter in an object.
22.95g / 15.45cm. Find density. Say if it sinks or floats.
1.49g/cm. The object sinks.
Density used units include...
g/cm3
g/mL
g/L
What kind of substance property is Density?
A Physical Property
Mass = 41g
Density = 3.2g/mL.
Find the volume.
12.81mL
Why is density important to understand?
To figure out if an object sinks or floats in water, & density is an important physical property of matter.
4.6g/12.5mL. Find the density. Does it sink or float?
0.368g/mL. It floats.
An object has the Density of 12.36 g/mL and the Mass of 6.52 g. What is the Volume?
1.8957055 mL
97kg / 105L. Find the density. Say if it sinks or floats.
0.92kg/L This object floats.
True or False? Mass changes with location.
False - mass does NOT change with location.
