Which of the following best defines density?
the mass per unit volume of a material
the weight of an object
the shape of an object
the size of an object
|
Which factor does NOT affect the density of a material?
type of material
shape of the object
temperature
pressure
|
What is the relationship between density, mass, and volume?
density = volume ÷ mass
density = mass x volume
density = mass ÷ volume
density = mass + volume
|
What happens when an object is placed in a liquid that has a greater density?
it floats
it sinks
its density changes
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 density of the object relative to the density of the liquid
the shape of the object
the volume 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 float
it will sink

|
What must be known to calculate the density of an object?
mass and volume
volume only
mass only
shape and volume

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 wood has more mass
the iron has less buoyant force acting on it
the iron is denser than water while the wood is less dense than water
|
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.
