Brand : Jianuo

Model : B5310

Description: Length 50m x 0.32

Dilatometer with clock gauge on baseplate (730x50x25 mm) for the quantitative measurement of the linear expansion of solid bodies depending on material, length and temperature.

Benefits

Metal tubes are fixed on the base plate and heated by hot water or steam flowing through them.

Base plate with fixing holder, leading bearing and measuring unit.

Transmission of linear expansion to a pointer by means of toothed rod and wheel.

Equipment and Technical Data

• Adjustable fixing holder measuring length 200 mm, 400 mm, 600 mm, diverse materials: brass, iron, glass.
• 2 tube holders to fasten flow in and flow out tubing
• Clock gauge: measuring range 0.10 mm,display resolution 0.01 mm

Heating a volume of air can lead to both an increase in volume and an increase in pressure. In this experiment the volume must be kept constant. This is achieved by marking the initial water level in limb a of the manometer and resetting the water level to this mark before reading the new pressure.

In a supplementary problem the temperature-pressure coefficient is calculated and compared with the reciprocal of the absolute temperature.

Benefits

• Real stand material for an esecially stable and safe setup
• Student-suitable experiment descriptions with reports available

Heating a volume of air can lead to both an increase in volume and an increase in pressure. In this experiment the pressure must remain constant. This is achieved by ensuring that the water level in both manometer limbs is the same before reading the volume change.

In the supplementary problem the expansion coefficient is calculated and compared with the reciprocal of the absolute temperature.

Benefits

• Real stand material for an esecially stable and safe setup
• Student-suitable experiment descriptions with reports available

The relationship which exists between the pressure and the volume of an enclosed gas on compressing it is to be determined.

Benefits

• Optimised for demonstration experiments: Transformation from horizontal into vertical direction
• Very good visibility: Big devices on uniform background
• Strong Magnets (at least 10 N) allow a safe mounting and therefore a very easy handling

Using a U-tube made of a piece of tubing and glass tubes, the students should show that the product of pressure and volume of a confined quantity of gas is constant.

Moreover, they should measure the difference in height between the water levels for pressure decrease and increase; the correlation should be illustrated with calculations and by investigating a diagram.

Benefits

• Student-suitable experiment descriptions with reports available

• Gas law of Boyle-Mariotte
• Gas law of Gay-Lussac
• Gas law of Amonton (Charles)
• Determination of molar masses according to the vapor density method
