Explore how the atmosphere produces various forms of precipitation, such as rain, hail, snow, and sleet. Learn about the role of heat, phase changes, and latent heat in the formation of different types of precipitation. Complete the handout on phase changes and states of matter for further understanding.
E N D
Aim: How does the atmosphere make the different types of precipitation? Do Now: - List as many different types of precipitation that the atmosphere creates
I. Vocabulary • Precipitation: • any form of water that falls from a cloud. • changes due to different temperatures. - rain - hail - snow -sleet How could I make this rain drop into a snowflake?
b) Heat – - transfer of energy from one object to another. - heat flows from High Energy to Low Energy. HIGH ENERGY LOW ENERGY
- transfers of energy (heat) cause phase changes Gains Energy Looses Energy • Melting Solid Liquid • Sublimation Solid Gas * Evaporation Liquid Gas * Condensation Gas Liquid • Deposition Gas Solid • Freezing Liquid Solid
c) Specific heat: the exact amount of heat (energy) need to raise the temperature of a substance by 10C. • Which is easier to heat up with a match (small amount of energy)? • Liquid Water • Lead pipe Cover ESRT
d) Latent (“hidden”) Heat: - Heat used to change the state of matter. - no change in temperature occurs because the energy is used to break molecular bonds. Latent Heat No Temperature Change!!
NO CHANGE IN TEMPERATURE DURING A PHASE CHANGE!!
II. ESRT Cover Shows the amount of energy either GAINED or RELEASED during the change in matter. ** Water is most dense at 3.980C (40C) in the - liquid phase -
Closure: • Please work to complete the handout on phase changes and states of matter from the back table (top bin)
