Energy

What changes should we make?

Many believe that man’s insatiable energy appetite is destroying the planet. In this unit we will therefore look not only at energy from a chemical perspective, but also from an environmental one. We’d like to know: 

Which energy sources are practical, abundant, and environmentally clean?

Which energy sources for vehicles are likely to replace gasoline?

Which is cheaper, gasoline or electricity?

How can energy transfer be measured?

How much energy is in a potato chip?

How much energy is involved during a phase change?

What units are used in energy and how do they relate?

What are enthalpy, free energy, and entropy, and why are they important? Tentative Schedule:
