Calculate ideal work (in J) when a single stream of 1 mole of air is heated and expanded from 25 C and 1 bar to 100 C and 0.5 bar. The temperature of the surrounding is 37 C.
Note: Assume air to behave as an ideal gas under these conditions and ideal gas heat capacity is dependent on temperature]

As a pendulum moves closer to the equilibrium position, how do the velocity, acceleration, and force change? the velocity decreases, the acceleration decreases, and the net force decreases. the velocity increases, the acceleration decreases, and the net force decreases. the velocity increases, the acceleration increases, and the net force decreases. the velocity decreases, the acceleration increases, and the net force increases.
