Chemical Building Blocks Chapter 2

Front

What happens to the particles of a liquid at 100°C?

Back

At 100°C, the particles of a liquid are moving rapidly and do not form regular patterns.

Front

What is sublimation?

Back

Sublimation is the process where a solid turns directly into a gas without becoming a liquid, often observed with snow in cold conditions.

Front

What is evaporation?

Back

Evaporation is the process of vaporization that occurs only at the surface of a liquid.

Front

What is the definition of volume in relation to gases?

Back

The volume of a gas is the amount of space it occupies.

Front

What is viscosity?

Back

Viscosity is the measure of a liquid's resistance to flow.

Front

What is condensation?

Back

Condensation is the process where a gas turns into a liquid.

Front

What is the difference between evaporation and boiling?

Back

Evaporation occurs at the surface of a liquid at any temperature, while boiling occurs throughout the liquid at a specific temperature.

Front

What is the relationship between temperature and the state of matter?

Back

Temperature affects the energy of particles, influencing whether a substance is solid, liquid, or gas.

Front

What is the principle of density?

Back

Density is the mass of a substance divided by its volume, often used to compare different materials.

Front

What is the effect of pressure on gases?

Back

Increasing pressure on a gas decreases its volume, according to Boyle's Law.
