The main difference between gases and plasmas has to do with

electrical conduction.

Most of the matter in the universe is in the

plasma state.

The faster a fluid moves, the

less its internal pressure.

Suspend a pair of Ping-Pong balls from two strings so there is a small space between them. If you blow air between the balls, they will swing

toward each other.

Which of the following bodies is comprised mostly of plasma?

Sun

A one-ton blimp hovers in the air. The buoyant force acting on it is

one ton.

When gas in a container is squeezed to half its volume and the temperature remains the same, the gas pressure

doubles.

In a vacuum, an object has no

buoyant force.

Atmospheric molecules do not fly off into outer space because of

Earth gravitation.

In drinking soda or water through a straw, we make use of

atmospheric pressure.

In a vacuum a marshmallow becomes

larger.

About how high can water be theoretically lifted by a vacuum pump at sea level?

10.3 m

Compared to the buoyant force of the atmosphere on a 1-liter helium-filled balloon, the buoyant force of the atmosphere on a nearby 1-liter solid iron block is

the same.

A bubble of air released from the bottom of a lake

becomes larger as it rises.

The flight of a blimp best illustrates

the principle of Archimedes.

A suction cup sticks to a wall. It is

pushed to the wall by the atmosphere.

When gas in a container is squeezed to half its volume, its density

doubles.

A balloon is buoyed up with a force equal to the

weight of air it displaces.

As a helium-filled balloon rises in the air, it becomes

bigger.

Alcohol is less dense than water. If alcohol is used to make a barometer on a day when atmospheric pressure is normal, the height of the alcohol column would be

more than 10.3 m.

Compared to the buoyant force of the atmosphere on a 1-kilogram helium-filled balloon, the buoyant force of the atmosphere on a nearby 1-kilogram solid iron block is

considerably less.

The energy source responsible for the motion of molecules that make up the atmosphere is

solar power.

It would be easier to pull evacuated Magdeburg hemispheres apart when they are

20 km above the ocean surface.

What change in pressure occurs in a party balloon that is squeezed to one-third its volume with no change in temperature?

The pressure will increase to three times its original pressure.

A plasma differs from a gas in that

it is electrically conducting.

A large block of wood and a smaller block of iron on weighing scales both register the same weight - 1 ton. Taking buoyancy of air into account, which has the greater mass?

wood

Suppose you are standing on a weighing scale and all of a sudden the atmosphere vanished. The reading on the scale would

increase.

The weight of a 1-square-meter column of air that extends from sea level to the top of the atmosphere is

101,000 N.

A helium-filled balloon released in the atmosphere will rise until

the balloon and surrounding air have equal densities.

Consider two mercury barometers, one with twice the cross-sectional area of the other. Neglecting capillarity, mercury in the smaller tube will rise

the same height as in the larger tube.

A column that extends from sea level to the top of the atmosphere contains a certain mass of air. If the same column instead had the same mass of water in it, the height of the water column would be

10.3 meters.

A column that extends from sea level to the top of the atmosphere contains a certain mass of air. If the same column instead had the same mass of mercury in it, the height of the mercury column would be

about 3/4 meter.

Compared to all liquids, solids, and gases in the universe, plasmas are the most

abundant.
