the heat loss is being regulated... so the pressure is high and constant....causing decrease in boiling point

thermistor i think.
because it is formed from semi conductors

hmmm.
how does increase in pressure decreases boiling point pls explain.

increases please....your idea is so required please
does it mean that ..increasing from 100 to 120 won't. make it boil longer clarify me please

relegation can otherwise be refreezing of ice.. according to the experiment, a thin wire can pass through ice without it(ice) breaking
