Sample questions

1. Question 1 Easy

   Fill in the right words.

   1. To breathe, we need … from the air. (oxygen / nitrogen / smoke)
   2. Water vapour is water as a …. (solid / liquid / gas)
   3. Granite, limestone and sandstone are …. (metals / plastics / rocks)
   Show the solution

   Answer:

   1. To breathe, we need oxygen from the air.
   2. Water vapour is water as a gas.
   3. Granite, limestone and sandstone are rocks.

   How it works: To breathe, we need oxygen from the air. Water vapour is water as a gas. Granite, limestone and sandstone are rocks.

2. Question 2 Normal

   What is this change of state called? Match each item (1–4) with the right option (A–E).

   1. water in the freezer turns into ice
   2. water bubbles in a pan on the cooker and turns into steam
   3. a puddle dries up in the sun
   4. there is dew on the grass in the morning

   • A) freezing
   • B) evaporation
   • C) condensation
   • D) melting
   • E) boiling
   Show the solution

   Answer:

   1. water in the freezer turns into ice → A) freezing
   2. water bubbles in a pan on the cooker and turns into steam → E) boiling
   3. a puddle dries up in the sun → B) evaporation
   4. there is dew on the grass in the morning → C) condensation

   How it works: water in the freezer turns into ice – freezing; water bubbles in a pan on the cooker and turns into steam – boiling; a puddle dries up in the sun – evaporation; there is dew on the grass in the morning – condensation

3. Question 3 Hard

   Fill in the right words.

   1. Warm air moves …. (downwards / upwards / sideways)
   2. We measure temperature with a …. (thermometer / ruler / scale)
   3. Water boils at about … °C. (100 / 50 / 0)
   4. Water freezes at … °C. (10 / 100 / 0)
   Show the solution

   Answer:

   1. Warm air moves upwards.
   2. We measure temperature with a thermometer.
   3. Water boils at about 100 °C.
   4. Water freezes at 0 °C.

   How it works: Warm air moves upwards. We measure temperature with a thermometer. Water boils at about 100 °C. Water freezes at 0 °C.
