Pressure | Forces | Physics A. Boyle’s Law Indicator Kit
This simple low-cost apparatus provides a means of demonstrating Boyle’s Law. It is not 100% accurate but is adequate for demonstrations giving students literally a ‘feel’ for increase in pressure against volume.
E8R07908 pack £16.44 B. Boyle’s Law Digital Apparatus
The Digital Boyle’s Law Apparatus provides a self contained, reliable and simple way of demonstrating Boyle’s Law. The volume may be reduced or increased by means of a 2.5ml syringe connected to a digital pressure sensor. The sensor output is calibrated to display the pressure in kPa on the easy to read LCD display. There is a measurable change in pressure for every 0.1ml change in volume allowing many data points to be taken and a graph plotted to confirm Boyle’s Law.
For demonstration purposes two 4mm sockets are provided to allow the pressure reading to be displayed on a large demonstration voltmeter meter (not supplied) and a length of tubing is provided to allow a larger syringe to be used if necessary.
Supplied with full instructions and one 9V PP3 battery.
E8R07372 C. Boyle’s Law (Horizontal Mount)
Designed as a smaller, more economical version of the Standard Boyle’s Law Apparatus.The apparatus consists of a horizontally mounted acrylic tube with a graduated scale along 1 side (scale graduated from 0 to 270cm3. The tube unit is sealed by a standard gas tap next to which is mounted a standard pressure gauge. The effective length of the tube is controlled by altering the position of a rubber stopper moved via a screw thread. Users can select the effective length of the tube by positioning the stopper and closing the gas tap. The volume of the tube can be read off the scale and printed against the corresponding pressure taken from the gauge. By varying the position of the stopper Boyle’s Law can be investigated. This unit has the advantage of not requiring oil to indicate the volume of air. The tube is made out of acrylic which is known to fail ‘safely’ if punctured.
