What compound has the lowest vapor pressure at 50 degrees celsius?
At 50 degrees Celsius, a compound with the lowest vapor pressure would be one with strong intermolecular forces like hydrogen bonding, such as water (H2O). These strong forces make it harder for molecules to escape into the gas phase, resulting in a lower vapor pressure compared to compounds with weaker intermolecular forces.
What is the flash point difference between diesel and gasoline?
The flash point difference between diesel and gasoline is that diesel has a higher flash point than gasoline. Diesel typically has a flash point of around 125-180 degrees Celsius, while gasoline has a flash point of around -40 to -60 degrees Celsius.
What gasoline has a density of 15 degrees?
Gasoline typically has a density of around 0.72-0.74 g/mL at 15 degrees Celsius.
At sea level water boils at 100 degrees Celsius while methane boils at negative 161 degrees Celsius Which has a stronger attraction between particles?
Water has a stronger attraction between its particles compared to methane. This is evident in the higher boiling point of water, as the stronger intermolecular forces require more energy to break the bonds between water molecules. Methane, being a lighter molecule, has weaker intermolecular forces which results in a lower boiling point.
Which has stronger attractions among its submicroscopic particles a solid at 25 degrees Celsius or a gas 25 degrees Celsius?
A solid at 25 degrees Celsius would have stronger attractions among its submicroscopic particles compared to a gas at the same temperature. In a solid, the particles are closely packed together and have strong intermolecular forces, leading to less movement and a more ordered structure. On the other hand, in a gas, the particles are far apart, have weaker intermolecular forces, and move freely in random directions.
What compound has the lowest vapor pressure at 50 degrees celsius?
At 50 degrees Celsius, a compound with the lowest vapor pressure would be one with strong intermolecular forces like hydrogen bonding, such as water (H2O). These strong forces make it harder for molecules to escape into the gas phase, resulting in a lower vapor pressure compared to compounds with weaker intermolecular forces.
How does a volatile substance evaporate faster than water?
A substance which is volatile does not have possess the strong intermolecular forces present in water. Water is held together by hydrogen bonding, where the positive end of one water molecule is strongly attracted to the negative end of another water molecule. This explains water's high boiling point of 100 degrees Celsius. A volatile compound will have either much less hydrogen bonding, or perhaps even the much weaker London dispersion forces as its only intermolecular force. This means less surface tension and a much lower boiling point. So it will evaporate much more quickly. Example: equal volume puddles of gasoline and water. The gasoline will evaporate much more quickly than the water puddle.
The compound CO2 sublimes readily at 25 degrees Celsius Which properties are usually associated with a compound that undergoes this kind of change?
A compound that sublimes readily typically has weak intermolecular forces, allowing it to transition directly from a solid to a gas phase without passing through a liquid phase. Such compounds often have low melting points and high vapor pressures, making them volatile.
What is the Specific gravity of gasoline vs temperature?
specific gravity of gasoline at 104 celsius
What chemical compound has its melting point as 104?
There are many compounds with a melting point of 104 degrees Celsius. These compounds often have differences in other characteristics, such as polarity, number of atoms, and its types of intermolecular interactions.
Why is more heat needed to vaporize water than gasoline?
Gasoline has a less boiling point (72 degree Celsius) While water has a bigger boiling point (100 degree Celsius)
Boiling points water and methane?
Water boils at a higher temperature than methane because water is a polar compound. Each molecule is held together chemically. Each molecule is held to other molecules by hydrogen bonding. With Methane, it is every molecule for itself.
Does gasoline freeze?
Yes but it is at -40 degrees to -60 degrees Celsius
What is the flash point difference between diesel and gasoline?
The flash point difference between diesel and gasoline is that diesel has a higher flash point than gasoline. Diesel typically has a flash point of around 125-180 degrees Celsius, while gasoline has a flash point of around -40 to -60 degrees Celsius.
Why is meso stilbene dibromide much less soluble than dl stilbene dibromide?
Meso stilbene dibromide is less soluble than di stilbene dibromide because it has a higher melting point. The melting point of meso stilbene is 238 degrees Celsius, while the other compound is only 114 degrees Celsius.
Gasoline freezes at - 37 Celsius what is the freezing point in Fahrenheit?
The freezing point of gasoline in Fahrenheit is -34.6°F.
What gasoline has a density of 15 degrees?
Gasoline typically has a density of around 0.72-0.74 g/mL at 15 degrees Celsius.
