- Describe the unique structure of the water molecule
*Help to create and control climate and weather●Influence the formation and modification of the land and seafloor●Enable essential chemicals to be transported to and within living organisms●Control many features of our physical environment, such as rain, snow, and the waves on oceans and lakes●Underlie the functioning of many aspects of modern society, ranging from cooling systems for automobile engines
- Explain how the water molecule gives water its unique physical and chemical properties
- Distinguish the difference between temperature and heat
- Describe how the density of water changes with temperature:
- going from solid to liquid to gas
- from 0oC to 100oC
- Define specific heat capacity
- Explain how water’s specific heat capacity might affect Earth’s average temperature
The following questions address a few of the fundamental Properties of Water on Earth. Answer the questions in your own words.
- Summarize a path that a water molecule would take to complete a journey through the water cycle. a) Begin in the ocean and how water moves through the ocean, atmosphere, lakes/rivers, and precipitation b)List important phase transitions and methods of transportation.
- Describe the shape of a water molecule and explain why it is considered to be a ‘polar’ molecule.
- Explain the difference between heat and temperature.
- Explain the difference between latent heat and sensible heat.
- Given 100 calories of heat energy, explain whether water or sand would experience a larger temperature change.
- Discuss whether you think the Earth would be warmer or cooler if liquid water did NOT cover Earth’s surface. Explain your answer.
