Parece mentira, mas é o Efeito Mpemba, observado desde Aristóteles em 300 a.C. A água quente congela mais rápido por 3 motivos: 1) Evapora mais rápido, então tem menos volume para congelar. 2) Cria correntes de convecção que distribuem o frio mais rápido. 3) Quebra o estado de super-resfriamento, onde a água fria fica líquida mesmo abaixo de 0°C. Testa em casa com duas forminhas iguais no freezer e me conta nos comentários. A ciência ainda discute por que isso acontece, mas o efeito é real.
