Em cada um dos recipientes abaixo há um litro de água pura a uma temperatura inicial de 80 °C. Nesses recipientes (1 e 2), adicionamos respectivamente dois bloquinhos A e B, de materiais diferentes e de mesma massa, 250 g, ambos à temperatura inicial de 20 °C. Depois que se estabeleceu o equilíbrio térmico, notamos que no recipiente 1 (onde está o bloquinho do material A), a temperatura final de equilíbrio foi de 60 °C, enquanto no recipiente 2(onde está o bloquinho do material B), a temperatura final de equilíbrio foi de 40 °C. Então responda:
A) Qual foi a quantidade de calor trocada entre o bloquinho A e a água? Considere que não há trocas de calor com o ambiente
