Is bromine a liquid element?
Yes, Bromine is a liquid at room, but it vaporizes away in some time as its boiling point is just above room temperature
Does the temperature of a boiling liquid increase as it boils?
No. Take water for example. Water boils at 100 degrees C. When water boils it becomes steam. This steam as soon as it is released is 100 degrees C also. The boiling point for a liquid is the point when it becomes a gas.
What do you do to turn a liquid into gas?
You must get the liquid to its boiling point then as it boils it will start to evaporate turning it into a gas.By agitating the molecules of the liquid (usually by heating it, but theoretically you could use sound or mechanical vibration) to the point where their kinetic energy is greater than the energy of the electromagnetic bonds holding the molecules in their liquid state.liquid can be converted to gas by heating it to its boiling pointYou can change it by heating it up for example when you heat up water. There is steam which is water in the state of a gas.To change a liquid to a gas, just heat the liquid, or decrease the pressure around the liquid! Once you reach the liquid's boiling point (such as 212 degrees Fahrenheit (100 Celsius) for water) the liquid begins a phase change, and turns into a gas. The process by which a liquid becomes a gas is called vaporization.Interestingly, if you decrease pressure around a liquid, then its boiling point decreases, while if you increase pressure, the boiling point increases. If you lower the pressure enough, water could boil at room temperature. This happens in space: if an astronaut jumped out into the void without a pressurized suit, he would feel the water on his eyes and tongue boiling away.
What is the relationship between intermolecular forces and vaporization points?
The greater the potential of a liquid's molecules to interact with each other through intermolecular forces, the lower the vapour pressure is going to be above the liquid (because molecules will preferentially stay liquid and interact with other molecules rather than fly away as a gas), and the lower the boiling point of the liquid. Therefore the relationship is an inverse one.
What is the technique used to separate ethanol from a mixture of ethanol and propanol?
Distillation would work. Those two liquids have different boiling points, and heating it up to the boiling point of the lowest liquid would cause it to boil away, leaving behind the other.
How can you separate a liquid from a liquid?
Distillation. Different liquids have different boiling points. Heat it up until the liquid with the lower boiling point boils away, then you're left with the other one.

The what remains constant when a liquid reaches boiling point?
The temperature. A liquid will increase in temperature until it reaches the boiling point temperature. At this temperature the liquid will become a gas. Under normal circumstances, the liquid cannot get any hotter than the boiling point without becoming a gas. So the liquid remains the same temperature until it has all boiled away.
What is the meaning of boiling and of boilingpoint?
Boiling is to heat an liquid to the point where it will turn from a liquid to a gas. Because the substance cannot be at temperature higher than its boiling point the temperature will remain that until all the liquid has been boiled away. That is why if I were to heat some alcohol and water the temperature would remain at about 60oC until all the alcohol had evaporated away. Then the temperature would go to 100oC and the water would boil. The boiling point of substance is the temperature at which the substance will turn from a liquid to a gas. This is about 100oC for water.

When a liquid becomes a gas the break away from one another?
During a liquid heating the intermolecular forces between molecules are first weakened and then supressed.As a consequence these molecules escape from the liquid and become a gas.Boiling occur at the boiling point and in the entire volume of the liquid; evaporation occur at the surface of the liquid and is possible at a temperature under the boiling point.
Does the temperature of a boiling liquid increase as it boils?
No. Take water for example. Water boils at 100 degrees C. When water boils it becomes steam. This steam as soon as it is released is 100 degrees C also. The boiling point for a liquid is the point when it becomes a gas.
How does he amount of energy change during boiling?
During boiling the temperatre of the boiling liquid does not go up. The energy input into the boiling liquid is taken away as the latent heat of evaporation by the escaping gaseous phase.
How is it possible for liquid water to turn into a gas at temperatures below its boiling point?
"Temperature" measures average thermal energy - but it's statistical. Outlier atoms will have sufficient energy to break away from the liquid state.

Which took more time heating the water from room temperature to boiling point or boiling all the water away?
boiling it
