1. A gas trapped in a cylinder does 540 J of work by expansion. At the end of the
process, the internal energy has decreased by 860 J.
a. How much energy was transferred as the heat between the gas and its environment?
b. Did the gas gain or lose energy in this transfer? Explain

Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. the winds blow from west to east in jet streams but the flow often shifts to the north and south. jet streams follow the boundaries between hot and cold air. the earth's rotation is responsible for the jet stream as well.
