보일의 법칙 검증

압력과 부피의 반비례 관계 실증하기

Gas Laws Intermediate (High School) 40 분 ~$15.00

목표

밀폐된 기체의 부피를 다양한 압력에서 측정하여 보일의 법칙(P1V1=P2V2)을 검증한다.

배경

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.

안전 경고

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

필수 개인 보호 장비

goggles

재료

  • 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)

장비

Retort stand and clamp Weights or books for applying pressure Ruler

실험 절차

1

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

5 분
2

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

5 분 Do not force the syringe
3

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

15 분
4

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

5 분
5

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

8 분

예상 결과

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.

정리

Return apparatus to storage. Dispose of graph paper drafts.
