RPA GCSE Science RP Density

What is density?

• The weight of an object

• The space that an object takes up

• The mass of an object divided by its volume

• The dimensions of an object

How do we calculate density?

• Divide the mass of an object by its volume

• Multiply the mass of an object by its volume

• Subtract the mass of an object from its volume

• Add the mass of an object to its volume

What is the unit for density?

• Grams per meter cubed

• Kilograms per centimeter cubed

• Grams per centimeter cubed

• Kilograms per meter cubed

How do we calculate the volume of a cuboid?

• Multiply the length, width, and height

• Divide the length, width, and height

• Add the length, width, and height

• Subtract the length, width, and height

How do we measure the volume of an irregular object?

• Using a ruler

• Using a vernier caliper

• Using a displacement can

• Using a measuring cylinder

What is the volume of the water in the measuring cylinder?

• 50 centimeters cubed

• 100 centimeters cubed

• 130 centimeters cubed

• 450 centimeters cubed

What is the density of the water in the measuring cylinder?

• 0.5 grams per centimeter cubed

• 1 gram per centimeter cubed

• 1.3 grams per centimeter cubed

• 4.5 grams per centimeter cubed

After you drop the irregular object into the displacement can, what do you use to measure the water?

• measruing cylinder

• beaker

• flask

• top pan balance

Why can't you use a ruler or calipers to find the volume of an irregular object?

• there are too many surfaces to measure, your measurement will not be precise

• You can't measure the volume of an irregular object

• You can use a ruler to measure length, width, and height

What piece of equipment do you use to measure mass

• top pan balance

• measuring cylinder

• Ruler

• calipers
