• 3

• 4

According to the picture, which one of the following is true?

• heat loss is happening

• heat gain is happening

• nothing is happening

• the changes of states is from liquid to solid

Tom filled half a pot with water to boil.

When he stopped heating the boiling water, the pot was less than half full. Why?

• Because some water has become steam

• Because some water has become vapor

• Because evaporation has taken place

• Because condensation has taken place

Ming Ming saw a puddle of water on his way home in the morning. When he returned in the afternoon, he noticed that the puddle had disappeared. What happened?

• The water of puddle had gained heat and changed into steam.

• The water of puddle had lost heat and changed into steam.

• The water of puddle had gained heat and changed into water vapour.

• The water of puddle had lost heat and changed into water vapour.

Which one of the following is NOT the example of evaporation in our daily lives?

• Raining

• Wet clothes under the Sun will dry up

• Wet floor will dry up after mopping

• The loss of water in a glass after a week

What is the similarity between evaporation and boiling?

• Both are heat gain processes

• Both are heat loss processes

• Both have boiling point

• Both have melting point

Which one is true about evaporation?

• It takes place throughout the liquid.

• Bubbles are formed throughout the liquid.

• The temperature of the remaining liquid remains the same during evaporation.

• It takes place at any temperature.

Which one of the following factor does not involve in the drying up of clothes?

• the condition of cloud

• the temperature of the surroundings

• the presence of wind

• the surface area
