FROM LECTURE 1:

a practice quiz is available online

The midterm will be held on March 3 and is 2 hours long

ENGG Lecture

Thermodynamics is the study of heat and power

Terms:

Dimension: A measurable property that cannot be defined in terms of anything simpler

o Primary: The most basic dimension that cannot be reduced to anything simpler

Length [L], Mass [M], Time [t], Temperature [θ], Amount of material [n]

o Derived: Dimensions that can be defined in terms of primary dimensions

Velocity (Lt-1), acceleration (Lt-2), Force (MLt-2), Work (ML2t-2), Power (ML2t-3)

Unit: A way of expressing a dimension.

o In SI:

Length

Meter (m)
