1.Un mol de gas ideal está confinado bajo una presión constante P=20 atm. La temperatura se cambia de 100°C a 25 °C. Cv=3/2R. Calcular q, w, ΔE y ΔH.

2. Calcular el cambio de energía interna, calor y trabajo expresado en Joules y calorías, que realizan 2 moles de un gas ideal con Cv= 5/2R en los siguientes procesos:
a) Expansión isobara (V1= 2 L, V2= 5 L, p = 3 atm)
b) Expansión isoterma (V1 = 2 L, V2 = 5 L, t = 27°C)
c) Transformación isocora.

3. Tenemos tres moles de un gas monoatómico a 300 K. Calcular el incremento de energía interna, el trabajo, el incremento de entalpía y el calor puestos en juego en los siguientes procesos:
a) Proceso a presión constante
b) Proceso a volumen constante
Suponemos que la temperatura final para ambos procesos es de 270 K

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
