Why boiling point is increased with the increase of external pressure?
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
What happens to the boiling point of a solution as the concentraion increases?
Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. The boiling point can be measured accurately using an ebullioscope.
What happens when you dd salt to warter when boling?
Adding any nonvolatile solute to water will lower the freezing point and raise the boiling point .... but not by very much. There is a myth that adding a bit of salt (NaCl) will raise the boiling point and cause to food to cook faster. The problem is that the small amount of salt added to boiling water by the average cook will have a negligible effect on the boiling point of the water. So why is salt added to boiling water? To make whatever is cooking in the water a bit salty. As for what happens.... Water boils when its vapor pressure is equal to atmospheric pressure. Adding salt decreases the vapor pressure of the resulting solution, which means that more energy is needed to force the solution to boil, and the boiling point is elevated. Boiling point elevation is a colligative property and depends on the total number of particles in solution. The increase in boiling point, DT, can be calculated ... DT = iKm ... where i is the van't Hoff factor, and indicator of how many particles come from a formula unit of solute. K is a constant. The boiling point elevation constant for water is 0.512 C/m. The symbol "m" stands for molality, a way of expressing concentration in moles of solute per kilogram of solvent.
In general as elevation increases from the ground up what happens to atmospheric pressure?
Pressure decreases. This is because atmospheric pressure is a measure of the weight of the atmosphere weighing down. If you are high in the atmosphere, much of the atmosphere is below you so the pressure from above will be very small.
What happens as you go up a mountain?
Increasing elevation leads to a lower amount of air, mass, weight and pressure. It can also lead to a decreasing temperature.
What is the boiling point of H30 plus?
It does not exist except as part of water - it does not exist in isolation so can have no boiling point as boiling happens when vapour pressure equals the external pressure.
What happens to the boiling point of a liquid if the pressure exerted on a surface is reduced?
The boiling point lowersas the pressure is lowered.
What happens at a liquid's boiling point?
Boiling. A liquid boils at a temperature at which its vapor pressure is equal to the pressure of the gas above it.
Why is a bag puffed up when you are 3000 meters high?
It was packaged at a lower elevation where the air pressure is higher. As you move to a higher elevation the external air pressure decreases, but the air pressure in the bag stays the same. So the bag "blows up" like a balloon because the pressure inside it much greater than the pressure outside. Same thing happens in your ears.
What happens at a substance's boiling point?
Its vapor pressure equals atmospheric pressure.
What happens to water if you lower its pressure?
you lower its boiling point.

What happens to fluid pressure as elevation increases?
it elevates unless you can control it. true
Does Increasing the pressure of a liquid lower its boiling point?
The boiling point of a liquid increases when atmospheric pressure is increased.
When boiler pressure increases what happens to the boiling point of water?
The boiling point of water is dependent on environmental factors and the presence of solutes. In this case the pressure of the system on the water serves to increase the boiling point of water. The higher pressures increase boiling points while lowering pressure decreases it.

How does boiling from evaporation?
Evaporation is much slower than boiling, and it can happen at any temperature (above zero Kelvin) whereas boiling only happens at the boiling point. Evaporation happens when a liquid molecule has enough energy to escape from the surface of a liquid - this is why you can smell perfume and why puddles disappear in warm weather As these molecules build up above the surface of the liquid, there is a build up of pressure. This is called the saturated vapour pressure. When the overall temperature of the liquid is high enough, the saturated vapour pressure increases until it is equal to atmospheric pressure - this is called the boiling point.
