Rajah di bawah menunjukkan sehelai kain yang dikeringkan di dalam rumah pada musim hujan.

Diagram below shows a piece of cloth which is being dried inside house during rainy season.

Apakah kesimpulan terbaik yang dapat dibuat daripada rajah di atas?

What is the best conclusion that can be made from the diagram above?

• Kehadiran angin akan membantu proses penyejatan

  The presence of wind will help in the evaporation process

• Lebih besar kawasan permukaan, lebih cepat proses penyejatan

  The bigger the surface area, the faster the evaporation process

• Semakin pantas kelajuan angin, semakin lambat kain kering

  The faster the speed of wind, the slower the cloth will dry

• Suhu persekitaran akan meyebabkan air menyejat lebih cepat

  The surrounding temperature makes water evaporate faster
