Question 1 options:
High Pressure (H=happy)
Sun
Atmosphere
Cold Front (blue triangles)
Nitrogen
Cumulus Clouds
Troposphere
Nimbus Clouds
Low Pressure (L=Lousy)
Warm Front (red semicircles)
1.
Lowest layer of Earth's atmosphere. Where we live. Where we find most weather.
2.
Fluffy, dense clouds mostly composed of water droplets.
3.
A cold air mass is replacing a warm air mass. Showers and thunderstorms form along leading edge or front.
4.
Dark clouds that have rain or snow falling.
5.
The layer of gases that surround the earth.
6.
Makes up 78% of Earth's atmosphere.
7.
A warm air mass is replacing a cold air mass. Air behind front is warm and moist. Slow moving, gradual rise or warm air over cold.
8.
Happens when air cools and it becomes denser causing to fall lower in atmosphere. Clear, sunny skies.
9.
Is necessary for evaporation to take place.
10.
Happens as warm air rises and becomes less dense. Cloudy skies and precipitation.

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
