Why does propanone has higher vapour pressure than ethanol at room temperature?

The intermolecular forces (IMFs) that attract propane molecules to eachother is far weaker than the IMFs of ethanol molecules. Consequently there is less of an energy barrier for a propane molecule to evaporate.
IMFs of propare are limited to the london dispersion forces, which are the weakest IMFs
IMFs of ethanol are the london dispersion forces as well as the dipole-dipole interaction (- charge on oxygen and positive on hydrogen) and hydrogen bonding (very strong IMF)

Does air pressure and temperature change with altitude?
Yes; the pressure and temperature decreases with higher altitude.
What happens to pressure and temperature the closer you move to the core?
it gets higher
Why are mantle rocks solid even though the Earth's interior temperature is very hot?
The melting temperature of materials is dependent on the pressure that is applied, whereby the higher the pressure, the higher the melting temperature. As such the rocks in the mantle are experiencing such a high pressure, that their melting point is driven up beyond the temperature within the Earth's mantle so they remain solid.
Can water be made to boil at 95 or 105C?
Yes. The temperature can be reduced by lowering the "atmospheric" pressure: for example by going up a mountain. The boiling point can be raised by increasing the pressure - in a pressure cooker, for example, or by dissolving a solute such as salt.
Is it possible for distilled water in liquid form reach a temperature of 105 degrees Celsius. why or why not?
Sure. Boiling point is related to pressure. Increase the pressure and boiling will occur at a higher temperature.
Why ethanol is the best solvent for recrystallization of urea?
because ethanol dissolve urea at slightly higher temperature and not dissolve the impurities
What are factors that affect gas pressure?
There are two factors that affect gas pressure. These factors are temperature and volume. Higher volume means lower pressure. Higher temperature means higher pressure.

What has a higher boiling point 1 propanol or propanone?
I think propane is higher??
What is the principle involved in pressure cooker?
At higher pressures, water boils at a higher temperature. A pressure cooker lets you cook at a higher pressure than regular saucepans so you can have a higher boiling temperature
Which is soluble in water propanone or 3-hexanone?
Propanone is more soluble, because it is smaller. the smaller the molecule the higher the solubility nursing student.
Does air pressure and temperature change with altitude?
Yes; the pressure and temperature decreases with higher altitude.
What is the relationship between the temperature and the pressure of gas?
If the temperature is low, then the molecules of the gas have less kinetic energy and thus it has low pressure. If the temperature is higher, then the molecules have more energy and thus the gas has higher pressure
How does pressure affect the temperature at which water boils?
There is a direct relationship between the temperature at which water boils and the air pressure on it. Higher pressure, higher boiling point. Lower pressure, lower boiling point.
How does temperature affect the rate of diffusion?
The higher the pressure, the more easily a chemical diffuses. And seeing as pressure and temperature are directly related, the higher the temperature the more easily a chemical diffuses, and vice versa. This is caused by everything "wanting" to be equal, if there is a higher pressure, then it will diffuse to an area of lower pressure.
How does pressure effects the time period of cooking food?
If you are referring to cooking with a pressure cooker, the higher pressure attained in this type of cooker allows the water to reach a higher temperature before boiling. This will cook food more quickly due to the higher temperature, which in turn is due to the higher pressure. Keep in mind that once water reaches the boiling point, the temperature remains constant; the only way to attain a higher temperature, then, is to increase the pressure.
What does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
At higher temperature the vapor pressure is higher.
