Hedef

Farklı sıcaklıklarda hava dolu bir balonun çevresini ölçerek Charles yasasını göstermek.

Arka Plan

Charles's law states that at constant pressure, the volume of a gas is directly proportional to its absolute temperature (Kelvin). By heating and cooling a balloon and measuring its size, the linear relationship between V and T can be confirmed.

Güvenlik Uyarıları

  • Handle hot water carefully
  • Do not use boiling water directly on the balloon

Prosedür

1

Inflate a balloon to a moderate size and tie it off. Measure its circumference at room temperature with string.

3 dak
2

Prepare three water baths: ice water (~5°C), room temperature (~22°C), and hot water (~60°C).

5 dak Handle hot water carefully
3

Submerge the balloon in ice water for 5 minutes. Remove and quickly measure circumference. Record temperature.

7 dak
4

Return the balloon to room temperature water for 5 minutes. Measure circumference.

7 dak
5

Submerge in hot water for 5 minutes. Measure circumference. Record temperature.

7 dak
6

Convert temperatures to Kelvin. Plot V (proportional to circumference³) vs T(K). Extrapolate to find absolute zero.

Beklenen Sonuçlar

The balloon should be visibly smaller in ice water and larger in hot water. Plotting estimated volume vs absolute temperature should give a straight line. Extrapolating to zero volume should approximate -273°C (absolute zero).

Temizlik

Drain water baths. Pop and dispose of balloons. Clean up any spills.
