Changes states of Water

Describe what happened when ice change to water

• Heat is loss, the particles cool down

• Heat is gain, the particles gain energy and vibrate vigorously

• Heat is loss, the particles gain energy and vibrate vigorously

• Heat is gain, the particles cool down

What is the differences between boiling and evaporation?

• Evaporation and Boiling occurs at any temperature

• Evaporation and Boiling occurs at 100°C

• Evaporation occurs at 100°C and boiling occurs at any temperature

• Evaporation occurs at any temperature and boiling occurs at 100°C

What is the similarities between boiling and evaporation?

• Water change to Ice

• Water change to water vapour/steam

• Water vapour change to water

• Steam change to water

Describe what happened during boiling/evaporation

• Heat is loss, the particles cool down, water vapour changes to water

• Heat is gain, the particles gain energy and vibrate vigorously, water vapour changes to water

• Heat is loss, the particles cool down, water changes to water water vapour

• Heat is gain, the particles gain energy and vibrate vigorously, water changes to water vapour

State the freezing point of pure water

• 100°C

• 10°C

• 0°C

• 1000°C

The process happened in the picture is called condensation. Explain. how it occurs.

• When cold water vapour from the air touches the cold surface of the bottle, it changes from liquid to gas.

• When cold water vapour from the air touches the cold surface of the bottle, it changes from gas to liquid.

• When warm water vapour from the air touches the cold surface of the bottle, it changes from gas to liquid.

• When warm water vapour from the air touches the cold surface of the bottle, it changes from liquid to gas.
