QUESTIONS AND ANSWERS GRADED A+
◉evaporation. Answer: -the process of liquid water becoming water
vapor
-is a COOLING process
◉condensation. Answer: -the changing of water vapor into liquid
water
- water molecules that leave vapor form
-is a WARMING process
◉saturation. Answer: -balance of solid, liquid and vapor(gas) forms
of water
-ex: fog
◉sublimation. Answer: -water molecules that leave frozen surfaces
and go into vapor form
-bypass liquid form
,◉deposition. Answer: -water molecules that leave vapor form and
go directly into solid ice form
- bypass liquid form
-ex: frost
◉latent heat. Answer: changing from water vapor into liquid water
or ice;
heat that is needed to change phase of a substance
◉3 types of latent heat. Answer: -Vaporization(Lv)- liquid to vapor
or gas; -water takes in 540 cal/g to vaporize from liquid to gas
-fusion or melting(Lf)- liquid to solid; water takes in 80 cal/g to melt
from solid ice to liquid
-sublimation(Ls)- solid to vapor or gas; ice takes in 620cal/g to
sublimate from solid to vapor; ex: dry ice
◉define shaeffer point. Answer: when water immediately becomes
ice
◉Converting Fahrenheit to celsius. Answer: degrees celsius =
5/9(degrees Fahrenheit - 32)
, ◉converting celsius to fahrenheit. Answer: 9/5(degrees celsius) +
32
◉converting from celsius to Kelvin. Answer: Kelvin = degrees celsius
+ 273
◉Pressure. Answer: ALWAYS increases with height
-temperature zig zags; is not constant
◉standard value for atmospheric pressure. Answer: 1013.25 mb =
1013.25 hPa = 29.92 in. Hg.
◉concept of air pressure in terms of mass of air above some level.
Answer: -the more air above a level, the greater the squeezing
effect(compression)
◉where is air more dense?. Answer: at earth's surface
◉what tool measures pressure?. Answer: barometer
◉higher barometric pressures are more associated with ___________.
Answer: colder temperatures
