The boiling point of alcohol depends on which type of alcohol you're using, as well as the atmospheric pressure. The boiling point decreases as atmospheric pressure decreases, so it will be slightly lower than published values unless you are at sea level. The ethanol boiling point—also known ...
What is the boiling point of ethanol and does it's boiling point relate to it's intermolecular attraction? How does boiling and melting affect the chemical bonds in an atom or molecule? What is hydrogen bonding and how might hydrogen bonding be used to explain the substantial difference...
What is the boiling point, in Celsius degrees, of 150 g of aluminum bicarbonate in 0.40 kg of water? What is the vapor pressure of ethanol at 16 degrees Celsius? Ethanol has a heat of vaporization of 38.56 kJ/mol and a normal boiling point of 78.4 ...
For baking muffins, the recommended condition of “OM 7”, 2 h at 175 °C, could not be used as the boiling point of the ethanol-based food simulants (78 °C) was below the recommended temperature. To keep the experimental procedure as simple as possible and reduce the risk of ...
摘要: Katti and Chaudhri 1 have published a set of measurements on the effect of electrical fields on the boiling points of methanol, ethanol, and isopropanol. This is an effect which can be calculated from the first principles of thermodynamics....

A sample of HgCl2 weighing 9.41g is dissolved in 32 .75g0fethanol(C_2H_5OH) .The boiling point elevation of the solution is 1.27℃. Is HgCl2 an electrolyte in ethanol? Show your calculations(K_b=1.20K⋅kg⋅mol^(-1)) 相关知识点: ...
(as in the case ofevaporation) but also throughout the volume of the liquid, where bubbles of gas are formed. The boiling point of a liquid is lowered if the pressure of the surrounding gases is decreased. For example, water will boil at a lower temperature at the top of a mountain, ...
