SE está diseñando una máquina de Carnot que usa dos moles de CO2 como sustancia de trabajo; el gas puede tratarse como ideal. El CO2 debe tener una temperatura máxima de 527 °C y una presión máxima de 5.00 atm. Con un aporte de 400 J por ciclo, se desea obtener 300 J de trabajo útil. a) Calcule la temperatura de la fuente fría. b) ¿Durante cuántos ciclos debe operar esta máquina para derretir totalmente un bloque de hielo con masa de 10.0 kg que inicialmente estaba a 0 °C, empleando únicamente el calor cedido por la máquina?
