Step 1 : Measure and pour 20cm3 of water into each container.

Langkah 2 : Ukur dan tuangkan 20cm3 air ke dalam setiap bekas.

Step 2 : Keep all the containers in the same place.

Langkah 2 : Letakkan kesemua bekas di tempat yang sama.

Step 3 : Record the time taken for water to evaporate from each container.

Langkah 3 : Rekod masa yang diambil untuk menyejat dari setiap bekas.

i) Record the stopwatch reading in the space provided.

Catatkan bacaan jam randik pada ruangan yang disediakan.
