A Heat Engine Using A Simple Gas Cycle 

The theoretical analysis of a heat engine that shows the process of a isobaric and isovolumetirc system.  The change in internal energy, heat, and work was calculated in the above picture based on the pressure volume and temperature given at each point. 

The Mass Lifter Heat Engine

This picture shows the relationship between a isotherm and adiabatic process in a engine. Given the pressure temperature and volume at each different point in the cycle we were able to calculate the change in internal energy, heat, and work. Using the total work and the heat that goes into the system we determined the the systems efficiency was 33 %.

Activphysics 8.7 Heat Capacity

Queston 6: The change in temperature was monitored in order to calculate the constant pressure molar heat capacity. Our rough estimations said that Cp=20.4J/(mol*K).

Question 7: The change in temperature from 200K to 800K was monitored in order to calculate the constant pressure molar heat capacity. Our rough estimations said that Cp=20.8J/(mol*K).

Question 8 shows the derivation of the constant pressure molar heat capacity from the change in the internal energy of a isobaric process.
