What else can I help you with?
What can you notice about the temperature of sea water during boiling?
The boiling point of sea water is higher compared with pure water. Temperature remain constant during boiling.
Why does halogens exist as a gas at room temperature?
They have a generally low boiling point, as compared to something like water with a higher boiling point and is a liquid at room temperature.
Which boils quicker liquid with high boiling point or liquid with low boiling point?
A liquid with a lower boiling point will boil quicker because it requires less energy to reach its boiling point compared to a liquid with a higher boiling point.
Which substance do you expect to have the greatest evaporation rate?
Substances with lower boiling points tend to have higher evaporation rates, as they can more easily transition from a liquid to a gas. Therefore, substances such as acetone or ethanol, which have low boiling points, would be expected to have higher evaporation rates compared to substances with higher boiling points like water or oil.
How does pressure change the boiling point of gasoline?
Increasing pressure raises the boiling point of gasoline, causing it to vaporize at a higher temperature compared to normal atmospheric pressure. Conversely, decreasing pressure lowers the boiling point of gasoline, leading to quicker evaporation.
Do alcohols have higher boiling points compared to other substances?
Yes, alcohols generally have higher boiling points compared to other substances due to the presence of hydrogen bonding between alcohol molecules.
Which has high resonance energy 'naphthalene or Diphenylmethane'?
Naphthalene has higher resonance energy compared to diphenylmethane, as naphthalene has a more extensive delocalization of electrons due to its two benzene rings being fused together. Diphenylmethane, on the other hand, has less delocalization due to the presence of a saturated carbon in the molecule.
What is the difference melting point of sodium iodide and naphthalene?
NaI has ions and has strong electrostatic force of attraction, hence high melting point. Naphthalene has weak van der Waals forces of attraction between the molecules and hence have low melting point.
What factors contribute to a substance having a higher boiling point compared to others?
The main factors that contribute to a substance having a higher boiling point compared to others are its molecular weight, intermolecular forces, and polarity. Substances with higher molecular weight and stronger intermolecular forces, such as hydrogen bonding, tend to have higher boiling points. Additionally, substances that are more polar also tend to have higher boiling points due to stronger attractions between molecules.
What is the reason for ch3br or ch3f having a higher boiling point compared to other compounds?
The reason ch3br or ch3f have higher boiling points compared to other compounds is because they have stronger intermolecular forces due to the presence of hydrogen bonding.
What can you notice about the temperature of sea water during boiling?
The boiling point of sea water is higher compared with pure water. Temperature remain constant during boiling.
What factor causes iron to have a higher boiling point than water?
The higher boiling point of iron compared to water is due to the strong metallic bonding between iron atoms, which requires more energy to break compared to the hydrogen bonds in water. This makes it harder for iron atoms to escape into the gas phase, resulting in a higher boiling point.
What is the Hypothesis of the melting and freezing point of naphthalene?
The hypothesis for the melting and freezing point of naphthalene could be that the melting point of naphthalene will be higher than its freezing point due to the typical behavior of most substances where solids melt at higher temperatures than they freeze. The hypothesis may also include factors like the purity of the naphthalene sample affecting its melting and freezing points.
A student measures the boiling point of rainwater and sea water.Which has the higher boiling point?
Sea water has higher boiling point,as it contains sodium chloride
Why does halogens exist as a gas at room temperature?
They have a generally low boiling point, as compared to something like water with a higher boiling point and is a liquid at room temperature.
What is the relation between the altitude compared to sea level and the boiling point of water?
In general, the higher the altitude, the lower the pressure, and the lower the pressure the lower the boiling point.
Are water's melting and boiling temperatures higher lower or average compared to other liquids?
This is only a relative appreciation.
