- Demonstrate the Adiabatic Gas Law
- Compare work done on sample to change in internal energy
- Measure γ, the ratio of specific heats (Cp/Cv)
- Investigate isothermal processes
- Output to computer interface via 5-pin DIN connector
The Adiabatic Gas Law apparatus is the perfect tool for teaching confusing thermodynamic processes. The Adiabatic Gas Law apparatus simultaneously measures volume, pressure and temperature, completely specifying the state of the gas. The gas can be rapidly compressed or expanded, creating nearly adiabatic conditions. Alternately, processes can be performed slowly, creating isothermal conditions.
||A linear potential divider is mounted on the side of the piston. A 5-Volt source from the computer is applied across the potentiometer element. The voltage from the commutator brush on the cylinder is used to indicate the position of the piston and the volume of the confined gas.
||A solid-state, piezoresistive device that forms part of a bridge circuit is mounted at the base of the cylinder.
||Mounted in the cylinder on the top of the base. The active element is fine nickel wire with a high surface-to-mass ratio. The wire's temperature and resistance change rapidly as the gas compresses or expands.
