Main Objectives:
- Be able to use energy conservation as expressed in the first law of thermodynamics
- Be able to define an adiabatic process
- Be able to calculate the work done during a thermodynamic process.
- Be able to explain the difference between thermal energy and heat
- Be able to explain why the specific heat capacity of all gases is not the same.
- Understand the meaning of heat of fusion and heat of vaporization
- Be able to work calorimetry problems involving phase change
- Be able to describe how heat is transferred via molecular collisions and how thermally
interacting systems reach equilibrium
- Be able to describe the molecular basis for pressure
- Be able to discuss the velocity distribution of the speeds of molecules in a gas
including the difference between vavg and vrms
- Be able to state the assumptions of kinetic theory and use them to explain phenomena
such as why the pressure in the tire increases when the car is driven.
