Como a água pode FERVER e, ao mesmo tempo, ficar cada vez mais GELADA? Parece contraditório, mas a resposta está na pressão. Normalmente, dizemos que a água ferve a 100 °C, mas isso só é verdade aproximadamente ao nível do mar, sob pressão atmosférica próxima de 1 atm. A ebulição acontece quando a pressão de vapor do líquido se iguala à pressão externa. Neste experimento, uma bomba retira parte do ar da campânula e reduz a pressão sobre a água. Com menos pressão externa, a água consegue entra
