process in the P-T diagram
☑ the area under the curve representing the
process in the P-V diagram
☐ the area under the curve representing the
process in the T-V diagram
The first law of thermodynamics is a statement of:

☐ conservation of (regular) momentum
☐ conservation of angular momentum
☐ conservation of mass
Ralph recently saw a sign while driving that said: "Caution: Bridge freezes
before road". He is wondering how that can be the case when the road and the
bridge are in thermal contact with each other. Plus, they are both in the same environment. What can you
tell him to help him understand?
Convection currents can remove heat from a bridge very efficiently.
