Verifikasi Hukum Boyle

Mendemonstrasikan hubungan terbalik antara tekanan dan volume

Gas Laws Intermediate (High School) 40 menit ~$15,00

Tujuan

Verifikasi hukum Boyle (P1V1 = P2V2) dengan mengukur volume gas yang terperangkap pada tekanan berbeda.

Latar Belakang

Boyle's law states that at constant temperature, the pressure and volume of a gas are inversely proportional. This experiment uses a closed syringe or J-tube manometer to measure gas volume at different pressures and confirm the relationship.

Peringatan Keselamatan

  • Do not apply excessive pressure to glass apparatus
  • Ensure all connections are airtight

APD yang Diperlukan

goggles

Bahan

  • Boyle's law apparatus or large syringe (1)
    60 mL syringe works
  • Pressure gauge (1)
    Or manometer
  • Rubber tubing (30 cm)
  • Graph paper (2 sheets)

Peralatan

Retort stand and clamp Weights or books for applying pressure Ruler

Prosedur

1

Set up the Boyle's law apparatus with a known volume of trapped air. Record the initial pressure and volume.

5 menit
2

Increase the pressure by adding mercury or pushing the syringe. Record the new pressure and volume.

5 menit Do not force the syringe
3

Take at least 8 readings at different pressures, both increasing and decreasing.

15 menit
4

Calculate PV for each reading. They should all be approximately equal.

5 menit
5

Plot P vs V (hyperbola) and P vs 1/V (straight line through origin) graphs.

8 menit

Hasil yang Diharapkan

The product PV should remain approximately constant (within 5% experimental error). The P vs 1/V graph should be a straight line through the origin, confirming the inverse proportionality.

Pembersihan

Return apparatus to storage. Dispose of graph paper drafts.
