- 1Explain cold, dew point, and warmThe dew point is the temperature at which condensation and evaporation rates are balanced. Any colder, or any more water vapour in the air, and condensation will start to win.
- 2Complete the picture drawn on the board, including labels, for how a cloud forms.n/a
- 3If there has been no rain in the forecast, explain what the weather would have likely been over the last 24 hours in order to wake up and see water droplets stickingIt was warm yesterday to make the air humid, and cold overnight so it got colder than the dew point temperature and the water condensed.
- 4Why does air cool in the upper atmosphere? What is equilibrium? Why does water condense onto your glasses when you come inside from recess in winter, but not when you go outside? What are three things that water adheres to in the sky when forming a cloud? What is the heat index? Why is it dangerous when it is hot AND HUMID outside in summer?n/a
- 5How does the cloud in a bottle demonstration work?When the air is pressurized, it is heated and so no condensation can happen. When the cap is released and the air expands, it cools and the vaopur condenses easily
- 6What is heat capacity? How are the heat capacities of water and sand different?Heat capacity is how much energy is needed to raise the temperature by 1 degree C. Sand has a lower heat capacity (it takes less energy to raise its temperature
- 7What is the difference between how heat traevels during condution vs. radiation? What happens when solar radiation hits a white surface? What is a convection cell? What is the name of the type of radiation that warm objects emit more of? If it is +2 degrees C but the windchill makes it feel like -6 degrees C, will a cup of water left outside freeze? True or false: Air is an insulator. True or false: Heat flows in fluids using convection.n/a
- 8Why does windchill make the air feel colder, even though the air hitting your face is the same temperature as if there was no wind?The wind removes the heat layer (boundary layer) around your body, like taking off a blanket while sleeping. Your body has to spend more heat to reheat the air, so you lose heat faster. This cycle continues as long as it stays windy.
- 9Explain this picture on Mars:
