Quando a pressão dentro de uma câmara de vácuo diminui, o ponto de ebulição dos líquidos também diminui. A ebulição acontece quando a pressão de vapor do líquido se iguala à pressão externa. No caso da água, essa pressão de vapor é relativamente alta mesmo em temperaturas moderadas. Por isso, ao reduzir a pressão do ambiente, a água atinge rapidamente a condição de ebulição, mesmo estando longe de 100 °C. Durante esse processo, a água não aquece: pelo contrário, ela esfria.
