Answer:
The first law of thermodynamics then reduces to
dQ = dW + dU ⇒ dU = −dW (1)
where dW is the amount of work done by the gas and dU is the change in internal energy.
Since the gas is expanding, the work being done by the gas is positive. Eqn. (1) then implies that the change in internal energy of the system must be negative, that is, the internal energy
is decreasing. The only true statements are then:
• The work done by the gas is positive, and no heat exchange occurs.
• The internal energy of the system decreases.
Answer:
When a cold polar air mass meets a warm tropical air mass they do not mix - they form fronts. The colder air mass is heavier than the warmer air mass, therefore the lighter, warmer air rises over the top of the heavier, colder air. As the warm air is forced to rise it cools.
