Science 10 Weather Dynamics Quiz #2 Outline Thursday, October 6th2011
Addressed Curriculum Outcomes:
- Identify questions to investigate that arise from considering the energy transferred within the water cycle (212-1)
- Plan experiments that can be used to determine the latent heat of fusion and vaporization for water (213-2)
- Using scientific theory, describe and explain heat transfer and its consequences in both the atmosphere and hydrosphere, relating this science to natural phenomena (115-2, 331-2)
- Describe and explain the effects of heat transfer on the development, severity, and movement of weather systems (331-4)
For this Quiz, you will be expected to understand and be able to do the following:
- Provide detailed definitions forthe following key terms (what is it, what unit(s) is it measured in, etc) Textbook p433 Glossary.
- Latent Heat of FusionLatent Heat of Vaporization
- Absolute Humidity (measured in grams of water per 1kg of air)
- Actual Humidity (measured in grams of water per 1kg of air)
- Relative Humidity (expressed as a percentage)
- Air Temperature°C (= Dry Bulb Temperature)
- SaturatedMoisture in g of water/kg of air (= Absolute Humidity or Dry Bulb Saturated Moisture)
- Dew Point in °C ( = Wet Bulb Temperature)
- Dew Point Moisture in g of water/kg of air ( = Actual Humidity or Wet Bulb Saturated Moisture)
- Describe an experiment that could be used to determine the latent heat of fusion and latent heat of vaporization of water.
What are heat of fusion and heat of vaporization, and what could you do in order to calculate these values for water?
- Calculate the Relative HumiditygivenAir Temperature (Dry Bulb Temperature) and Dew Point (Wet Bulb Temperature) using a provided table of Amount of Water Vapour in Saturated Air at Standard Atmospheric Pressure such as on page 431 in your textbook (See Relative Humidity Worksheet)
- Remember that
1) Saturated Moisture = Dry Bulb Saturated Moisture = ABSOLUTE HUMIDITY
Dew Point Moisture = Wet Bulb Saturated Moisture = ACTUAL HUMIDITY
2) RELATIVE HUMIDITY = ACTUAL HUMIDITY x 100
ABSOLUTE HUMIDITY
- Name 2-3 instruments used to measure weather properties, and explain how they work. (See Assignment)
- Properties of weather include: Humidity, Air Pressure, Precipitation, Temperature, and Wind
