So, why have most of us been taught that the boiling point of water is constant? And, if it is not constant, how can it be used as a 'fixed point' for the calibration of thermometers? History of science has the answers.关键词:...
What causes a substance to have a low boiling point? Why is it necessary to add more heat to reach boiling point than to maintain boiling? Explain how adding a solute affects the vapor pressure of the solvent. Why does water have a higher boiling point compared to ethanol?
The reason for this is its high volatility and its low boiling point of 56°C or 132.8°F. The molecular structure of acetone makes its molecules less likely to stay in their original liquid form and quickly escape into the air. Moreover, the high vapor pressure of acetone also reflects ...
Why does water have high entropy? Describe how to prepare 1.0 L of a 0.10 M NaCl solution. Explain how to prepare 1.0 L of isotonic saline, which is a 0.92% NaCl solution. What is the chemical make up of salt? Why does chlorobenzoic acid have a lower freezing point than benzoic aci...

High heatis useful when you want to get the water to reach boiling temperature quickly. Once you've got where you want, reduce the heat to medium (for boiling) or medium-low (for simmering). Once the water is at a rolling boil, more heat will only make it boil away faster. ...
The second bottle might be used for bathing to stave off disease, an urgent but less immediate need. The third bottle could be used for a less urgent need, such as boiling some fish to have a hot meal, and on down to the last bottle, which the castaway uses for a relatively low pr...
