25 Questions
What term is used to describe the degree of expansion divided by the change in temperature of a material?
Coefficient of thermal expansion
How does the thermal coefficient of expansion affect the volume of water as temperature increases?
Increases nonlinearly
Which statement accurately describes the composition of seawater compared to river water?
Seawater has a lower percentage of bicarbonate ions than river water.
How does the increase in temperature affect the separation between constituent particles in a substance?
Increases the average separation
What is a primary reason behind the rise in sea level due to global warming?
Thermal expansion of water
Why is seawater denser than fresh water?
The added weight of salts
What is the range of pH for seawater?
7.5 to 8.4
How does the freezing point of sea water change with increasing salinity?
It decreases
What did Sir Edmond Halley propose about the origins of sea salt?
It is carried into the sea by rivers and concentrated through evaporation
Which property describes matter's tendency to change in volume in response to a change in temperature?
Thermal expansion
What is the term for the process of water changing from a gas to a liquid?
Condensation
Why is solid water (ice) less dense than liquid water?
As a result of water expanding below 4°C
What would happen if water behaved like other liquids?
Ice sinking to the bottom of a glass in a drink
What term describes the property of water being attracted to other water molecules?
Cohesion
What is the process called when water changes directly from a gas to a solid without becoming a liquid?
Sublimation
What property of water is described as the enhanced attraction of water molecules at the surface of a body of water?
Surface tension
How does surface tension affect the ability of a small object to remain suspended on the surface of water?
Enhances the ability for the object to remain suspended
Which phenomenon is related to the cohesive properties of water and showcases water 'climbing' up a straw?
Capillary action
What limits the effectiveness of capillary action according to the text?
Gravity
Which property is NOT directly associated with surface tension based on the information provided?
Coefficient of thermal expansion
Why does an oil molecule not dissolve in water?
Due to the net electrical charge across the molecule.
What is the main reason behind water having a high specific heat capacity?
Being a relatively light molecule.
Which substance typically has a higher specific heat capacity than liquid water?
Hydrogen (H2) gas.
What is the average salinity of seawater in the world's oceans?
3.5%
How does hydrogen bonding contribute to the properties of water?
Enhances water's ability to absorb heat without a drastic temperature change.
