Materials Vernier data-collection interface Logger Pro or LabQuest App Vernier Gas Pressure Sensor Vernier Stainless Steel Temperature Probe 125 mL Erlenmeyer flask 400 mL Supply of hot and cold water Procedure The efficiency, of an engine (for diatomic gas) can be calculated using. The pressure and volume of the engine's gas is measured during the entire cycle, and the work done by the engine is computed. This process is known as an isothermal expansion - so named because the data were collected slowly enough that the temperature of the gas in the system remained constant. 0000004003 00000 n 0000012579 00000 n Most macrostates correspond to many microstates. Intro: when an engine runs, it pumps pistons that move up and down and provide energy to the engine to it to go.

A beaker or a pot filled with full water was boiled and was kept boiling throughout the experiment and served as the hot bath, while for the cold bath, another beaker or pot was filled with ice and water and its temperature was maintained by adding ice or water. This effect was observed as a rise in the object on the platform so is the piston height from state B to C. However, if the air chamber can is placed in the cold bath, the temperature and volume will decrease.
