Why does water boil at a higher temperature than butter, which is non-polar? Why does AsH3 have a higher boiling point than PH3? Why does Cl- have a larger ionic radius than Ca2+ ? Why are anions always larger than the atoms from which they are formed?
Why does water have a higher boiling point than alcohol even though water is a smaller molecule?Boiling Point:The boiling point of a compound is the temperature at which the vapor pressure becomes equal to the atmospheric pressure. At this temperature, the substanc...
You might be aware that the boiling point of water is 100oC. Upon reaching the boiling point, although the water is visibly more agitative, the sound is now subdued. This has left many geeks (like us) and researchers baffled by this strange phenomenon. Also Read:How Does A Pressure Cook...
The water itself does the rest. To see why, think about the pressures in the pipes on each side of the boiler. The right-hand pipe holds hot water at, say, 82oC. The pressure at the bottom is then: Similarly, the pressure at the bottom of the left-hand pipe, which holds water ...

"Well,then just pour out some water!" his father said. Gary___thoughtfully. "At first,you set too many goals,"said his father. "It's just like the large kettle full of water. You didn't have enough wood,___ you couldn't boil the water. If you want to make the water boil,the...
As you lower the pressure, the boiling point falls. If you lower the pressure enough, water will boil at room temperature. If you plot out the solid-liquid-gas behavior of a substance like water on a graph showing both temperature and pressure, you create what's called a phase diagram fo...
