6.2 OpenScied Lessons 1-6

Front

What are solid particles?

Back

Solid particles are closely packed together and have a fixed shape and volume. They vibrate in place but do not move freely.

Front

What are liquid particles?

Back

Liquid particles are close together but can move past one another, allowing liquids to take the shape of their container while maintaining a fixed volume.

Front

What are gas particles?

Back

Gas particles are far apart and move freely, filling the entire space of their container. They have no fixed shape or volume.

Front

What happens to water particles when they evaporate?

Back

When water particles evaporate, they gain energy, start moving faster, and change from a liquid state to a gas state.

Front

What is a closed system?

Back

A closed system is one where no matter can enter or leave. In a closed system, the total mass remains constant.

Front

What is evaporation?

Back

Evaporation is the process by which liquid water changes into water vapor (gas) due to an increase in temperature or decrease in pressure.

Front

What is condensation?

Back

Condensation is the process by which water vapor (gas) cools and changes back into liquid water.

Front

What is the difference between evaporation and boiling?

Back

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

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, including processes like evaporation, condensation, and precipitation.

Front

What is the role of temperature in evaporation?

Back

Higher temperatures provide energy to water particles, increasing their movement and the rate of evaporation.
