Classwork - Intro to Density

What is the formula used to calculate the density of an object?

• Density = Mass / Volume

• Density = Volume / Mass

• Density = Mass x Volume

• Density = Mass + Volume

Which unit is commonly used for density in the metric system?

• g/cm³

• kg/m

• cm/g

• ml/g

If an object floats in water, what can you infer about its density compared to water?

• Its density is less than water

• Its density is more than water

• Its density is equal to water

• Its density is zero

Which property is most useful for identifying a pure substance?

• Color

• Density

• Shape

• Size

If an object displaces 10 ml of water when submerged, what is its volume?

• 5 ml

• 10 ml

• 15 ml

• 20 ml

Given that the density of liquid water is 1 g/milliliter, will a rock with a density of 0.83 g/cm³ float or sink in water?

• Float

• Sink

• Stay suspended

• Dissolve

What is the density of water in g/mL?

• 1 g/mL

• 0.1 g/mL

• 10 g/mL

• 100 g/mL

A golfball has a density greater than 1 g/cm³. What does this mean if placed in water?

• It will sink

• It will float

• It will dissolve

• It will expand

Is oil more or less dense than water?

• Reasoning

• The oil floated on top of the water.

• Claim

• Because the oil floated on the water, I know it is less dense.  Objects less dense than water float. 

• Evidence

• Oil is less dense than water.

The boat is ​ (a)   dense than water.

• less
• more
• as
