What is the formula for calculating density?
Remember, density involves mass and how much space it occupies.
Convert 1 m³ of water into kilograms.
Recall: The density of water is 1000 kg/m³.
What is density defined as?
Think about how much mass is packed in a given volume.
True or False: Specific weight is the weight per unit mass.
Consider how weight is related to volume, not directly to mass.
A tank holds 500 liters of oil with a density of 850 kg/m³. Calculate the specific weight of the oil.
Use the specific weight formula with gravitational acceleration.
Compare the densities of fresh and seawater. If fresh water is 1000 kg/m³ and seawater is 1025 kg/m³, explain why objects float differently in them.
Recall how density affects buoyancy and floating.
