Solución: De la primera ley de la termodinámica, el cambio en la energía interna de un gas viene dado por \Delta U=Q+W donde Q es la energía agregada al gas al calentarlo, y W es el trabajo realizado sobre el gas , dado por W=-P\Delta V donde P es la presión del gas y V es el cambio de volumen del gas a medida que se realizaba el trabajo. Convirtiendo la presión de la atmósfera a Pascal, P=1.3atm\cdot\frac{101325Pa}{1atm} P=1317235Pa Sustituyendo los valores, \Delta U=16000-1317235\left(0.200 -0.100\derecha) \Delta U\aprox2828J Respuesta: Opción d
