Sample P has a fixed volume but no fixed shape. Which state is P?

Liquid
Solid
Gas
It cannot be classified from these properties.

Why can a trapped gas be compressed substantially without removing particles?

There are large gaps between its particles that can decrease.
Each gas particle shrinks.
The particles stop existing temporarily.
The gas becomes a vacuum.

A body's temperature rises. What happens to the average kinetic energy of all its particles?

It increases.
It decreases.
It must stay unchanged.
It becomes zero.

A model assigns 45 J to random particle motion and 30 J to interparticle position. What internal energy does the model assign?

75 J
15 J
45 J
30 J

Pure water freezes while its temperature remains constant. Which energy-transfer statement is correct?

Energy transfers from the water to the surroundings.
Energy transfers from the surroundings to the water.
No energy transfers because temperature is constant.
The transfer direction reverses every second.

Substance Q fills a sealed container and occupies the whole available volume. Which state is Q?

Gas
Liquid
Solid
Both liquid and solid

Which particle model explains why a solid keeps its shape?

Its particles are held in an ordered arrangement and vibrate about fixed positions.
Its particles move freely through the whole container.
Its particles continually move past one another.
Its particles have no forces between them.

Particles in sample R have a greater average kinetic energy than particles in sample S. Which sample has the higher temperature?

Sample R
Sample S
They must have the same temperature.
Their temperatures cannot be compared.

A particle-energy ledger assigns 28 J to random motion and 17 J to interparticle position. What internal energy does it record?

45 J
11 J
28 J
17 J

A pure liquid boils at constant temperature. What must happen during the boiling interval?

Energy transfers into the liquid while its temperature stays constant.
Energy transfers out of the liquid while its temperature rises.
No energy transfers because the temperature is constant.
The liquid freezes without any transfer.
