En el campo una geóloga bebe su café matutino de una taza de alumi-
nio. La taza tiene una masa de 0.120 kg e inicialmente está a 20.0 °C
cuando se vierte en ella 0.300 kg de café que inicialmente estaba a
70.0 °C. ¿A qué temperatura alcanzarán la taza y el café el equilibrio
térmico? (Suponga que el calor específico del café es el mismo del
agua y que no hay intercambio de calor con el entorno.)
