Why does petroleum ether have boiling point range while diethyl ether has a boiling point?
Why is the boiling point of water is unusually high for such a small molecule
Question 6 (1 point) Water has a relatively high boiling point due to London dispersion forces. True O False
Suppose the boiling point of pure water at high altitude is 88.46 °C. Use the Clausius-Clapeyron equation to determine the atmospheric pressure (atm) at this high altitude. The normal boiling point of water is 100.0 °C at 1 atm, and its heat of vaporization is 40.7 kJ/mol.
Boiling Point vs. Atomspheric Pressure The boiling point of water depends on atmospheric pressure. At high altitudes, atmospheric pressure is lower, and hence water boils at a slightly lower temperature. Plot a graph by hand for the following data treating atmospheric pressure as the independent variable. Atm Press (mm of Hg) Temperature (Co) 750 752 754 756 758 760 762 764 766 768 99.63 99.70 99.78 99.85 99.93 100.00 100.07 100.15 100.22 100.29 a) Calculate the slope of the line....
s. Consider propane, which has a normal boiling point of -42.0°C and a heat of vaporization of 19 kJ/mol. What is the vapor pressure at 25.0°C? 6. Atmospheric pressure on the surface of Mars averages 600 Pa (6 mbar) Use the phase diagram for water below to determine the boiling and melting points for water on the surface of Mars, assuming an atmospheric pressure of 800 Pa. Note that this chart uses a logarithmic scale, so the axes major unit...
23. A climber has carefully measured the boiling point of water at the top of a mountain and found it to be 95°C. Calculate the atmospheric pressure at the mountaintop. The boiling point of water at 1 bar pressure is 99.82°C and the heat absorbed in vaporizing 1 mol of water at constant pressure is 40.67 kJ mol-1
Compared to the freezing point and boiling point of water at 1 atmosphere, a solution of a salt and water at 1 atmosphere has a:
The region behind the elongation zone has high pH in the surface. Briefly explain what is the underlying biochemical basis for this and how does this high pH impact on cell development in this region?
A kettle containing 6kg of water has just reached its boiling point. How much energy, in joules, is required to boil the kettle dry?
