bcoz of the intermolecular hydrogen bonding in methyl alcohol the vapour pressure of the molecule equalises the atmospheric pressure at higher temperatures. there is no hydrogen bonding in dimethyl ether and hence the molecule escapes at relatively lower temperatures.
Decreasing the pressure -APEX
The temperature is 60,3 oC.
Boil the water till its boil . then it will be free from co2. ai bit dau
Place the container of water in a vacuum & it should start to boil at room temperature.

How high is high? The boiling temperature depends on the pressure of the atmosphere above the liquid. The higher you go the lower is the atmospheric pressure, and so the boiling temperature. Methanol boils at 64.7°C (148.4°F) at 760mmHg, about sea level.
Because the pressure of the atmosphere in the flask is lowered by the vacuum; a liquid will reach it's boiling point when the pressure of the atmosphere is equal to or less than the vapor pressure of the liquid.
It's in a tree ether by a long log or a tree stump.
Methanol has a Boiling point under standard conditions of 64.7 °C, and ethanol of 78.4 °C. You I can boil off vapor and collect Methanol and Ethanol, and use that cooled back down to liquid form and preform a test.
yes,at room temperature by decreasing the pressure we can boil the water.

If heated to a high enough temperature yes, rock will boil.
While liquid nitrogen theoretically could be used as a wart remover, this is not done in practice due to the difficulty of maintaining nitrogen in the liquid state. Commercial wart remover products contain dimethyl ether and propane. These liquified compounds (which are gaseous at room temperature and pressure) boil upon releasing the pressure in the container, thereby causing a dramatic cooling effect. Because liquid nitrogen is so cold and can cause severe frost bite, it is used only by physicians to kill warts.
When the temperature reaches the correct temperature (boiling point).
