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)

Based on Reference Table H which sample has the highest vapor pressure?
The sample with the highest vapor pressure will be the one with the highest temperature listed in Reference Table H. Generally, higher temperatures result in higher vapor pressures for a substance.
Which two qualities affect atmospheric pressure?
Temperature and altitude are two qualities that affect atmospheric pressure. As temperature increases, air molecules move faster and create higher pressure. At higher altitudes, there are fewer air molecules above, leading to lower pressure.
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.
Why does ethanol burn differently than ethanol and water mixed?
Ethanol burns differently than a mix of ethanol and water because water has a higher boiling point compared to ethanol. Water will absorb heat during combustion, which can lower the overall temperature and affect the efficiency of the burning process. This can lead to a slower and less complete combustion compared to pure ethanol.
How does pressure affect temperature?
Increasing pressure typically results in an increase in temperature through the process of adiabatic heating. This is because higher pressure compresses gas molecules more closely together, increasing their energy and therefore their temperature. Conversely, decreasing pressure usually leads to a decrease in temperature as gas molecules move further apart and lose energy.
What has a higher boiling point 1 propanol or propanone?
I think propane is higher??
What factors affects 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.
Based on Reference Table H which sample has the highest vapor pressure?
The sample with the highest vapor pressure will be the one with the highest temperature listed in Reference Table H. Generally, higher temperatures result in higher vapor pressures for a substance.
What are factors that affect gas pressure?
Gas pressure is affected by factors such as temperature, volume, and the number of gas particles present. For instance, increasing the temperature of a gas will increase its pressure, while decreasing the volume of a gas will increase its pressure as well. Additionally, having more gas particles in a given space will lead to higher pressure.
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
What does the vapor pressure vs temperature graph reveal about the relationship between vapor pressure and temperature?
The vapor pressure vs temperature graph shows that as temperature increases, the vapor pressure also increases. This indicates that there is a direct relationship between vapor pressure and temperature, where higher temperatures lead to higher vapor pressures.
How can a substance boil to a higher temperature with the same rate of heat provided?
A substance can boil at a higher temperature when the external pressure is increased. This phenomenon is seen in pressure cookers, where the higher pressure raises the boiling point of water. The substance requires more energy to overcome this increased pressure and reach the higher boiling temperature.
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 causes has pressure?
The answer depends on what kind of pressure. If you mean the pressure exerted by gasses on the walls of a container (a balloon, for example), pressure is created by the motion of the molecules of gas. Temperature and density of the molecules are factors. Higher density results in higher pressure. Higher temperature creates more molecular motion, thereby creating higher pressure.
What are 3 factors affect air pressure?
The factors are: -The volume that the air takes up (the greater the volume the less the pressure) -The amount/number of molecules of air (the more gas the higher the pressure) -The temperature (the higher the temperature the higher the pressure) and that's it lol
