Which state of matter undergoes changes in volume most easily?

According to Charles’s law, when the temperature of a gas at constant pressure is increased, its ______________________.

The change from liquid to solid, or the reverse of melting, is called ______________________.

An uncovered pot of soup is simmering on a stove, and there are water droplets on the wall above the back of the stove. What sequence can you infer has occurred?

In cold climates, the amount of snow on the ground may decrease even if the temperature stays below zero degrees Celsius. The process that best explains this event is _________________________.

The state of matter in which particles are arranged in either a crystalline or an amorphous form is ________________.

The greater the speed of gas particles in a container, the __________________________________________.

Pressure can be measured in units of _____________________.

According to Boyle’s law, when the pressure of a gas increases at constant temperature, its volume ________________.

The state of matter in which particles are arranged in the least organized manner is the ______________.

When a substance cools, it loses _________________ energy to its surroundings.

Sublimation is the change of a solid directly into a _____________.

A liquid’s resistance to flowing is called _____________.

________________ occurs when a liquid changes to a gas below its surface as well as at the surface.

Particles in a liquid move around just as freely as particles in a solid.

In crystalline solids, the particles are not arranged in a regular pattern.

At its boiling temperature, the particles of a liquid are moving so slowly that they begin to form regular patterns.

Pieces of dry ice (solid carbon dioxide) become smaller through the process of condensation.

Water vapor is a colorless gas that is impossible to see.

The amount of space that matter fills is its

A ___________ will always take the shape and volume of its container.

The _______________ is a measure of the average speed of the particles in a substance.

A(n) ___________________ has a definite volume but no shape of its own.

The ________________ of a gas is the force of its outward push divided by the area of the walls of its container.

Viscosity is the inward force among the molecules of a liquid.

A(n) amorphous solid has a definite melting point.

Both gases and liquids are fluids.

ALL solids have a closely packed, fixed arrangement of particles.
