How is it measured
How is the volume of a cube measured?
Volume = (length) X (width) X (Height) OR V = lwh
What is mass?
Mass is the amount of matter in an object.
What is the formula for density?
what is mass divided by volume equals density
If an irregular-shaped object is placed in a graduated cylinder that has 20 mL of water and then the water displaces to 22 mL, what is the volume of the object?
Final volume (22 mL) – Initial volume (20 mL) = 2 mL
What is volume measured in?
cm3
How is mass measured?
You have to use a balance.
What is weight?
Weight is the measure of gravitational force on an object.
What is the formula for volume?
What is length x with x hight=volume
If an object has a mass of 165.3 g and a volume of 97 cm3, what is the density of the object?
1.704 g/cm3
The ratio of mass and volume is?
Density
How is density measured?
Mass divided by volume.
What is volume?
Volume is the amount of space matter takes up.
What is the formula for mass?
What is volume x density= mass.
When you mix oil and water, why do the water sink and the oil float on top?
The water is denser than the oil which causes it to
sink.
True or False: Matter always has the same density regardless of how much or how little of the matter is present?
true
How is weight measured?
Mass times the acceleration of gravity.
What is density?
Density is the measure of an object per unit
volume.
How do you figure out water displacement??
Take an initial reading of grad cylinder
Put object in
See new reading
Subtract first reading from the second reading
Find the volume of a box with a length of 5cm, the width of 10cm, and a height of 2cm
100cm3
Specific gravity is useful because we can calculate if an object will blank or blank in water?
sink or float
How can you find the volume if we know the mass and density?
mass divided by density
What is true about an object that has a lot of mass?
It has a lot of matter
Explain how you know an object is more dense than another one.
have more molecules in the same amount of space
Calculate the volume of a hairbrush if the water in the graduated cylinder was 123 mL before the hairbrush was put in and the volume of the liquid after the hairbrush was submerged rose to 256 mL.
133 cm3 or 133 mL
Density is always measured in units of...
g/cm3
