What else can I help you with?
When using a water bath to determine the boiling point of a substance the substance's boiling point must be what?
Below 100 °C.
What happens to the melting and boiling point of a substance if it contains impurity?
If the impurity has a higher boiling point then the boiling point of the mixture will also be slightly higher, and vice versa.
What is the effect of soluble volatile substance on the boiling point of a water solution?
A soluble volatile substance will lower the boiling point of a solution. The volatile substance will boil at a lower temperature than the water component, thus causing the solution to boil at a lower temperature.
True or false a boiling point is a chemical property of a substance?
False. A boiling point is a physical property of a substance, not a chemical property. Chemical properties describe how a substance interacts with other substances to form new substances, while physical properties are characteristics that can be observed or measured without changing the substance's chemical composition. Boiling point is the temperature at which a substance changes from a liquid to a gas at a given pressure, which is a physical characteristic.
What is the boiling point degrees in Fahrenheit?
At sea level the boiling temperature of water is 212o Fahrenheit. At different air pressures the boiling temperature changes. Higher air pressures require higher temperatures to boil. For example, if you go to a mountain top you could lower air pressure until water could boil at say 99o Fahrenheit. If you change substances, from water to something else, that substance would have its own individual boiling temperature, the point at which it changes from liquid to gas.
When you change the amount of a substance the time it takes to reach the boiling point then what happens?
The lower the amount of substance, the faster it reaches the boiling point. The more the amount of substance, the longer it takes to reach the boiling point. Hope that this is what you wanted to know! :)
Does acidity effect the boiling point?
No, acidity does not directly affect the boiling point of a substance. The boiling point is mainly determined by the intermolecular forces within a substance and the external pressure exerted on it. Acidity may affect the chemical properties of a substance, but it does not have a direct impact on its boiling point.
If the boiling point of a certain amount of a liquid is 150 degrees then what is the boiling point of twice that amount of the liquid?
The boiling point of twice the amount of liquid will remain 150 degrees. The boiling point of a substance is determined by the chemical properties of the substance itself, rather than the quantity of the substance.
How does substance's density affect its boiling point?
A relation between the boiling point and density doesn't exist.
What 2 factors affect the boiling point of water?
Pressure & Temperature :) Apex
What is the relationship between the heat of vaporization and boiling point of a substance?
The heat of vaporization is the amount of energy needed to change a substance from a liquid to a gas at its boiling point. The higher the heat of vaporization, the higher the boiling point of the substance.
What changes when the amount of a substance changes?
When the amount of a substance changes, it can affect the concentration, density, and reactivity of the substance. In chemical reactions, changing the amount of a substance can also impact the equilibrium position and the rate of reaction. Additionally, changing the amount of a substance can influence its physical properties, such as melting point, boiling point, and solubility.
Does changing the amount of sugar affect the boiling point of water?
Yes. Dissolved sugar increase the boiling point.
What are the considerations must be made when examining the boiling point?
When examining the boiling point, consider the type of substance (e.g. organic, inorganic), intermolecular forces present, atmospheric pressure, and purity of the substance. These factors can affect the boiling point of a substance.
How does impurities affect the boiling point of liquid?
Let's say substance A is the substance and substance B is the impurity. The boiling point of the mixture would be somewhere between that of A and B, depending on the amount of impurities in the mixture.
How does pressure affect the boiling point of a substance?
Pressure affects the boiling point of a substance by either raising or lowering it. When pressure is increased, the boiling point of a substance also increases because it requires more energy to overcome the higher pressure. Conversely, when pressure is decreased, the boiling point of a substance decreases because less energy is needed to overcome the lower pressure.
Did corn meal affect the boiling temperature of water the same as sugar?
Each substance has a different effect on the boiling point.
