It's not that simple, and is equivalent to asking if cars speed up or slow down at the bottom of a hill: it depends on which direction they're going.

Which has the higher boiling point Br2 or icl?

Yes, because BrBr2 is ionically bonded, while the Br2O is covalently (molecularly) bonded. Ionic bonds are stronger than covalent (molecular) bonds. This means that BeBr2 has stronger attraction between molecules and it will take more energy (heat) to "unstick them" into the gas phase. Because there is more heat needed to get BeBr2 boiling, it has a higher boiling point.


What do most thing do when they get colder?

the molecules slow down as it nears the point of fusion


What is the relationship between the altitude and the boiling point?

The boiling point of water will be greatest at that point on Earth that is the closest to sea level. Boiling point of water depends on the atmospheric pressure. The boiling point of water varies depending on the weather. At low atmospheric temperatures due to weather or due to being up a mountain, the water will boil below its "normal" boiling point of 100 oC


Does water molecules speed up or slow down when water vapor returns to the liquid water s?

Condensation. The transformation of water vapours in liquid water is called condensation, a change of phase.


What does boiling and melting point of gases mean?

The boiling point is the temperature at which something changes states between gas and liquid - thus, whether or not something is a gas is irrelevant to the boiling point. The boiling point can also be referred to as the point of condensation - condensation is the point at which a gas becomes a liquid, boiling when a liquid becomes a gas. The melting point is the temperature at which a substance changes states between liquid and solid - can also be known as the freezing point or point of solidification. As an example, nitrogen is over 70% of our atmosphere, and is a gas at room temperature (usually around 20 degrees Celsius). However, its "boiling point" is -195 degrees Celsius. If you cool it all the way down to -195, it would condense - become a liquid. If you managed to cool it beyond that, to -215 degrees Celsius it would become a solid. So, the "boiling" and "melting" points are simply the same as the point of condensation and freezing point.

Does boiling point of water slow down with salt?

No, adding salt to water increases the boiling point, not slows it down. The presence of salt in water disrupts the formation of hydrogen bonds between water molecules, requiring more energy to overcome these disruptions and reach boiling point.


What is group trend of boiling point in IA group?

The boiling point decrease from lithium to caesium.


what are the changes in the boiling point of water in high air pressure?

When air pressure increases, the boiling point of water also increases. This is because higher air pressure pushes down on the water, making it harder for the water molecules to escape into the gas phase. As a result, more heat is needed to bring the water to its boiling point.


Why does it take the water longer to boil when it has salt in it?

When salt is added to water, it increases the boiling point of the water, requiring it to reach a higher temperature to boil. This is because the salt disrupts the formation of water vapor molecules, which slows down the boiling process.


Can boiling point of acetone be lowered if placed in a vacuum?

Yes, the boiling point of acetone can be lowered if placed in a vacuum, as reducing the pressure lowers the boiling point of a substance. This is because at lower pressure, there is less external pressure pushing down on the liquid molecules, allowing them to escape into the vapor phase more easily.


When high speed molecules mix and collide with slower speed molecules the high speed molecules do what?

Slow down and the temperature drops.


Why doesnt sucrose have a boiling listed?

Sucrose does not have a boiling point listed because it undergoes thermal decomposition before it reaches a boiling point. When heated, sucrose breaks down into its constituent molecules of glucose and fructose, along with other compounds. This decomposition process occurs before sucrose reaches a boiling point.


Why boiling point of noble gases increase down in the group?

The melting and boiling points increase down the group because of thevan der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.


Do the halogens have a higher boiling point going down the group and why is that?

Yes, halogens have a higher boiling point going down the group. This is because the atomic size increases with atomic number, leading to stronger London dispersion forces between molecules as the size increases. Consequently, more energy is required to overcome these forces, resulting in higher boiling points.


What happens to the boiling point of a substance when you go higher above sea level?

The boiling point of a substance decreases as you go higher above sea level because the atmospheric pressure decreases. At higher altitudes, there is less pressure pushing down on the liquid, causing it to boil at a lower temperature.


What is the difference between boiling water and decomposing water?

Boiling water is the process in which water reaches its boiling point and turns into vapor, while decomposing water involves breaking down water molecules (H2O) into its constituent elements, hydrogen and oxygen. Boiling water is a physical change, while decomposing water is a chemical change. Boiling water is reversible, while decomposing water is typically irreversible.


How do the boiling points of the noble gases change as you go down?

As you go down the group of noble gases, the boiling points generally increase. This is due to the increase in molecular weight and London dispersion forces between the heavier atoms. Helium has the lowest boiling point, while radon has the highest boiling point among the noble gases.
