Air is forced over a heating element in the apparatus. The temperature indicator shows the change in air temperature. The orifice meter measures the airflow. A voltmeter and ammeter are used to monitor the heater's input. This setup allows for the determination of the air's specific heat.

Experimental Objective

The primary goal of this experiment is to determine ?, the ratio of specific heats of air, and to understand the adiabatic and isothermal expansion processes.

calculate ?, the ratio of specific heats of air, and to gain insight into adiabatic and isothermal expansion processes.
