Density

What two types of measurements make up DENSITY? 

• Mass and Volume
• Temperature and Mass
• Grams and Centimeters
• Volume and Weight

If an object is huge, then it's density must be...

• A majority of mass and little-to-no volume
• Extremely heavy making it sink in water 
• Low, so it will float 
• Size does not determine the density of an object

Look at this image.  Which object has the LOWEST density in water? How? 

• The Ping Pong Ball because it floats to the top 
• The bolt because it has sunk to the bottom
• The soda cap because it is not just full of air like the Ping Pong ball

What makes a black hole so special in regards to size and its density?? 

• Black holes are small, yet have extremely high densities
• Black holes are small with extremely low densities 
• A black hole has density and can sink to the bottom
• A black hole is the size of our Sun and is dense

What is the mathematical formula to solve for density? 

• D = m/v
• D = m - v
• D = m +v
• D = m(v)

Metals such as Aluminium (Al) have a low density. 

• True
• False
• What's Aluminium? 
• Hagerman is the GOAT

Metals such as Titanium (Ti) have a high density.

• True
• False
• What's Aluminium? 
• Hagerman is the GOAT 

Archimedes used density to discover if the crown of gold was real because

• Substances have their own unique densities
• Substances can change densities depending on their size
• Substances can change densities depending on their mass
• Substances can change densities depending on their volume

What units measure density? 

• grams (g)
• grams per milliliter (g/mL)
• grams per centimeter (g/cm)
• milliliter (mL)

Why do objects sink or float in H₂O? 

• Because their densities are higher or lower than compared to water
• Because their densities are using gravity to pull down
• Because their densities are heavier or lighter
• Because their mass and volumes are equal
