Equipment and technical data

• Bushing with clamping screw to hold on support material.

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.

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

An enclosed amount of gas is to be compressed by the pressure of a plunger, and an investigation is to be made as to which relationship thereby exists between the pressure of the gas and the pressure force acting on a defined area.

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
• Demonstrative measurement of forces with large circular dynamometers with a fixing magnet and ball-bearing pulley with two cord grooves for two measuring ranges

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.

Accessories
Data acquisition set with Cobra3 Basic unit for recording the measured data by means of a PC.

Perfect for student experiments.

Function and Applications
Cobra SMARTsense is the ideal solution for inexpensive digitalization of science teaching. The sensors connect wirelessly (Bluetooth) or wired (USB) directly to the student’s digital end device (smartphone, tablet or desktop PC). Measurement data can also be recorded without a connection to an end device using the offline measurement function and read out at a later time. Using the free and award-winning measureAPP measurement software for iOS, Android and Windows, measured values can be easily recorded and graphically displayed. If more evaluations are needed, the measureLAB measurement software for Windows and macOS can be used.

Measure the absolute pressure with this sensor. In the classroom you can perform glycolysis or measure the hydrostatic pressure.
