Properties of Ocean Water

Ocean water has a high salt content. Which term describes the amount of salt dissolved in water?

• heat capacity

• salinity

• density

• pressure

Why does it take more energy to change the temperature of water than air?

• because ocean water is salty

• because ocean water has high heat capacity

• because ocean water has low heat capacity

• because of the high concentration of dissolved oxygen in ocean water

Which of the following samples of ocean water would be most dense?

• a very warm and very salty sample

• a moderately warm and moderately salty sample

• a moderately cold and moderately salty sample

• a very cold and very salty sample

If some ocean water has low salinity and a high temperature, what can we tell about its density?

• It has high density.

• We would need more information to determine its density.

• It has low density.

• It has a moderate density.

Which of the following can NOT be found dissolved within ocean water?

• Lithium

• Oxygen

• Sodium Chloride

• Carbon Dioxide
