Location:

PL2 Newton Lab

Instructor:

Zehao, Pan

Instructions:

A cylinder is filled with air and a Pressure Sensor is attached. The piston is plucked by hand and allowed to oscillate. The oscillating pressure is recorded as a function of time and the period is determined. The ratio of specific heat capacities is calculated using the period of oscillation, according to Ruchhardt’s method.

Equipment:

Heat engine/gas law apparatus, large rod stand, 45 cm long steel rod, dual pressure sensor, 850 universal interface, Pasco capstone software.
