Math Problem Statement
Uma massa de 10 kg de gás refrigerante R-134a enche um recipiente rígido de 1,348 m3 a uma temperatura inicial de -40°C. O recipiente é então aquecido até a pressão de 200 kPa. Marque a alternativa que apresenta a temperatura final e a pressão inicial, respectivamente. Selecione a resposta: a T= 70,03 ℃; P=51,25 kPa b T= 64,30 ℃; P=56,86 kPa c T= 60,00 ℃; P=100,25 kPa d T= 66,30 ℃; P=51,25 kPa e T= 66,30 ℃; P=100,25 kPa
