Density of Regular Objects

What is the correct definition of denstiy?

• The amount of mass per area

• The weight per unit volume

• The amount of matter in an object

• The mass per unit volume

What is the correct unit for density?

• Joules per kilogram

• Kilograms per newton

• Kilograms per meter cubed

• Kilograms per meter squared

Which of the following is the least dense?

• Air

• Liquid

• Aluminium

• Copper

An object will float in a liquid if it is

In order to find the density of a regular object you must (check all that apply)

• Find the volume

• Calculate the weight

• Measure the mass

• Place it in a measuring cylinder

• Divide the mass by volume

To find the density of an irregular object you must (check all that apply)

• Find the weight

• Measure the length

• Place in a measuring cylinder that contains a volume of liquid

• Calculate the difference in volume before and after placing the object inside

• Find the mass and divide it by the volume

Which of the following is a risk of the density required practical?

• The object may get hot and burn you

• Water may spill on the floor

• Glass could get too hot and explode

• The fluid may be harmful or hazardous
