तापमान के साथ गैस के आयतन परिवर्तन को मापना
उद्देश्य
विभिन्न तापमानों पर हवा से भरे गुब्बारे की परिधि मापकर चार्ल्स का नियम प्रदर्शित करें।
पृष्ठभूमि
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.
सुरक्षा चेतावनियाँ
- Handle hot water carefully
- Do not use boiling water directly on the balloon
आवश्यक PPE
सामग्री
-
Latex balloons (3)Same size
-
String (1 m)For measuring circumference
-
Ice (1 kg)
-
Hot water (2 L)Various temperatures
उपकरण
प्रक्रिया
Inflate a balloon to a moderate size and tie it off. Measure its circumference at room temperature with string.
Prepare three water baths: ice water (~5°C), room temperature (~22°C), and hot water (~60°C).
Submerge the balloon in ice water for 5 minutes. Remove and quickly measure circumference. Record temperature.
Return the balloon to room temperature water for 5 minutes. Measure circumference.
Submerge in hot water for 5 minutes. Measure circumference. Record temperature.
Convert temperatures to Kelvin. Plot V (proportional to circumference³) vs T(K). Extrapolate to find absolute zero.
अपेक्षित परिणाम
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).
सफाई
Drain water baths. Pop and dispose of balloons. Clean up any spills.
