Cause Of the Strange Thermal Properties of Water
What is the cause of the strange thermal properties of water?
Group of answer choicesthe covalent bonds making up the water molecule which bind the atoms together very strongly
the molecule is very polar and so has multiple strong hydrogen bonds that hold the molecules together very strongly
the fact that there are is a huge amount of it on Earth and that it is gathered into the oceans

Which of the following water properties is responsible for causing the sea breezes that keep Irvine cooler during the hot summer months?
Group of answer choicespowerful solvent
high surface tension and cohension
high specific heat and heat capacity
high latent heat of vaporization

How does the latent heat of vaporization of water help us regulate our body temperatures when we sweat?
Group of answer choicesBecause energy (heat) is added to our skin by the water molecules in our sweat as they evaporate
Because energy (heat) is removed from our skin by the water molecules in our sweat as they evaporate
Because energy (heat) is removed from our skin by the water molecules in our sweat as they condense

The two graphs below show the density of freshwater (on the left) and the density of seawater (on the right) vs temperature. Use the graphs to help you select the TRUE statement below.
Group of answer choices
Unlike freshwater which is most dense at 4 oC, the density of seawater continues to increase until it reaches its freezing point.
Seawater is less dense than freshwater at all temperatures.
Freshwater density is more sensitive to changes in temperature than seawater density (i.e. freshwater density changes more dramatically as temperature increases).

We will discuss desalination as a source of freshwater in more detail next week. Do some quick research online to work out which of the following statements about desalination is FALSE?
Group of answer choicesDesalination takes a huge amount of energy so can worsen climate change if that energy is generated with fossil fuels.
Desalination poses no risk to marine life along the coast.
Desalination will not help inland states such as Nevada!
Desalination can provide California with more freshwater but it will be much more expensive than our current water sources.
