6.3 Part 1 Test

What is humidity?

• the amount of water vapor in the air

• the mass of an object

• the "real feel" temperature outside

• the amount of precipitation that fell to the ground

What is density?

• the total amount of mass in an object

• how fast particles are moving

• how closely particles are packed together in a given space

• when water vapor turns back to liquid

What is evaporation?

• When liquid particles slow down and become solid

• When liquid particles gain energy and become gas

• When gas particles lose energy and become a liquid

• When solid particles gain energy and become a liquid

What causes condensation?

• when ice crystals in the air reflect light

• when gas particles gain energy and spread out

• when liquid water particles gain kinetic energy

• when water vapor particles cool down and lose energy

How is heat transferred through conduction?

• when particles are touching/colliding and transferring their energy

• when light is absorbed into objects giving them energy

• when heat is lost from an open system

• when gases turn directly to solids

How is heat transferred through radiation?

• when energy transfers through particle collisions

• when the ground heats the air above it

• when light is absorbed into objects increasing their energy

• when particles become more closely packed together

Why does warm air rise?

• the particles are less dense and more spread apart

• the air has more water vapor than it can hold

• the particles are more dense and closely packed together

• the air has less heat and rises up

What are "cloud condensation nuclei" or CCN?

• the ice crystals that water vapor can turn into

• the types of tall clouds that produce hail

• small solid particles in the air that water vapor can condense on

• gases in the air that can also be found in clouds

What happens to a warmed parcel of air as it rises into the atmosphere?

• it gains energy from the sun and rises higher

• it transfers energy to the colder air surrounding it

• it gains too much humidity and creates rain

• its particles become less and less dense until it separates completely
