States of Matter and Energy

Front

What is the state of matter characterized by having a definite shape and volume?

Back

Solid

Front

What process describes the transition of a substance from a solid directly to a gas?

Back

Sublimation

Front

What happens to the movement of water molecules as ice melts?

Back

The molecules in the solid are unmoving in a rigid lattice. As the ice melts, the molecules start to vibrate, and then release from the lattice structure, moving freely as they drift farther apart to form a liquid.

Front

What occurs to water when it evaporates due to heat from the Sun?

Back

Water becomes a gas as it absorbs energy from the Sun.

Front

Which state of matter has particles that have more energy than the other states?

Back

Gas

Front

What is the state of matter that has a definite volume but takes the shape of its container?

Back

Liquid

Front

What is the term for the energy required to change a substance from a solid to a liquid?

Back

Heat of fusion

Front

What is the term for the energy required to change a substance from a liquid to a gas?

Back

Heat of vaporization

Front

What is the primary difference between solids, liquids, and gases in terms of particle arrangement?

Back

Solids have closely packed particles in a fixed arrangement, liquids have closely packed particles that can move past each other, and gases have widely spaced particles that move freely.

Front

What happens to the energy of particles as they transition from a solid to a gas?

Back

The energy of the particles increases.
