Temperature and Density

Briefly describe the overall relationship between temperature and density.

• Lower temperature water has higher density, warmer water has lower density

• Lower temperature water has lower density, warmer water has higher density

What happens when you increase the temperature of ocean water?

• the density increases

• the density decreases

• the water sinks

• the salinity increases

In addition to salinity, what factor affects the density of seawater?

• depth

• latitude

• temperature

• money

What is the temperature, salinity, and density like at the surface zone of the ocean (top) as compared to the deep zone (bottom) of the ocean?

• colder temperature, more salinity, and more dense

• colder temperature, more salinity, and less dense

• warmer temperature, less salinity, and less dense

• Warmer temperature, less salinity, and more dense

The amount of mass an object has in a certain volume ​ (a)  

• density

• solubility

• solid

• liquid

• gas

What happens when you increase the salinity of ocean water?

• the temperature increases

• the salt amount decreases

• the density increases

• the density decreases

When heat is added to a solid, liquid, or gas, how will the particles in the substance react?

• contract, move slower, take up less space

• expand, move a bit quicker, and take up more volume

• expand, move slower, and take up more space

When a substance is cooled or heat is taken away, what will the substances particles do?

• contract, move slower, take up less volume

• expand, move quicker, take up more space

• contract, move faster, take up less volume

When heat was added to the homemade thermometer, the liquid increased its volume (amount of space it takes up)

• true

• false

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
