a) Inferens : suhu mempengaruhi isipadu gas
Inference: The temperature affects the volume of the gas
b) Hipotesis: Semakin tinggi suhu, semakin bertambah isipadu gas
Hypothesis: The higher the temperature, the larger is the volume of gas
c) Tujuan: untuk mengkaji hubungan diantara isipadu dan suhu apabila tekanan tetap
Aim: to investigate the relationship between the volume and temperature for a fixed mass of gas at a constant pressure.
