Which of the following best defines density?
the shape of an object
the mass per unit volume of a material
the size of an object
the weight of an object
|
Which factor does NOT affect the density of a material?
pressure
type of material
temperature
shape of the object
|
What is the relationship between density, mass, and volume?
density = mass x volume
density = mass ÷ volume
density = volume ÷ mass
density = mass + volume
|
What happens when an object is placed in a liquid that has a greater density?
it sinks
its density changes
it floats
it dissolves
|
What is the main factor that determines if an object will float or sink in a liquid?
the mass of the object
the volume of the object
the density of the object relative to the density of the liquid
the shape of the object
|
An object with a density of 5 g cm-3 is placed in a liquid with a density of 2 g cm-3. What will happen?
its density will change to match the liquid
it will sink
it will float
it will dissolve
|
What must be known to calculate the density of an object?
shape and volume
mass and volume
volume only
mass only
|
Why does a 1 kg block of iron sink in water while a 1 kg block of wood floats?
the wood takes up more space
the iron has less buoyant force acting on it
the iron is denser than water while the wood is less dense than water
the wood has more mass
|
What physical property determines if an object sinks or floats?
|
Describe the key factors that determine whether an object will float or sink when placed in a liquid.
|
Outline the steps to calculate density from experimental mass and volume measurements.
