What is density?
Think about how heavy something is compared to its size.
Calculate the density of an object that has a mass of 50 grams and takes up a volume of 25 cm³.
Use the formula Density = Mass/Volume.
What is the formula to calculate density?
Check which option represents mass per unit volume.
True or False: A substance with a density greater than 1 g/cm³ will float in water.
Consider how density affects buoyancy.
A balloon filled with helium is less dense than the surrounding air. If the balloon has a mass of 5 grams and a volume of 3 liters, calculate its density. Will it float in air?
Compare the density of the balloon to that of air.
A gold ingot has a mass of 250 grams and a volume of 12.8 cm³. Compare its density to that of water to determine if it will sink.
Remember water's density when making your comparison.
