Work, Heat, and Internal Energy
Students will define work and heat in thermodynamic contexts and understand their relationship to internal energy.
Key Questions
- Differentiate between heat and work as forms of energy transfer in a thermodynamic system.
- Calculate the work done during expansion or compression of a gas.
- Explain how internal energy is a state function, unlike heat and work.
