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.
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.
the molecules slow down as it nears the point of fusion
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
Condensation. The transformation of water vapours in liquid water is called condensation, a change of phase.
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.
The boiling point decrease from lithium to caesium.
Slow down and the temperature drops.
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.
no. it does not any impurity in water and other all substances rises its boiling point and slows down its melting point . So salt will raise the boiling point of water rather than lowering it
The molecules slow down.
The molecules slow down.
Several things: First, what are you trying to boil? Different solutions have different boiling points based on their chemical composition. If you mean water, you can drop the boiling point by adding solutes to the water (salt, sugar, etc). Also, the altitude at which you are trying to boil the water can affect it's boiling point (due to vapor pressure). But Billy is cooler than

The boiling point of the mixture is higher than the boiling point of pure water; this slows down the evaporation of the coolant.
The friction (with the air molecules) would slow it down.
A definition of boiling point is when the vapor pressure of the liquid equals the ambient atmospheric pressure, thusly if you increase the pressure the vapor pressure must also increase and to do this you have to increase the temperature. Shinolaman
