The student takes the following steps :
Murid itu menjalankan langkah-langkah berikut :
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.
