How much salt would one need to add to 1 kg water to change the boiling temperature by 5C?
approximately 286 grams of NaCl......OR.....4.9 moles
What else can I help you with?
What element would melt in boiling water?
all the elements that has low boiling point than of the water.
Why is temperature of boiling water cannot be measured using an alcohol thermometer?
Alcohol thermometers are not suitable for measuring the temperature of boiling water because alcohol has a lower boiling point than water. The alcohol inside the thermometer would evaporate before reaching the temperature of boiling water, therefore providing an inaccurate reading.
Is boiling water irreversible?
From a thermodynamics standpoint, it depends how the process is carried out. If the system (the water) and the surroundings remain close to equilibrium during the entire process then the water boils reversibly. So if the change in temperature is approximately zero throughout the process and the process takes an infinitely long amount of time to carry out you can reversibly boil water.If you were asking whether water vapor can turn back into liquid water, then yes the process of turning water into water vapor is reversible.
A student takes some water in a beaker and heats it over a flame for determining its boiling point He keeps on taking its temperature readings He would observe that the temperature of water?
Increases until it reaches 100 degrees Celsius, at which point it would begin to change phase into gas and stop increasing in temperature.
What is the boiling point of a single water molecule?
A single water molecule doesn't have a boiling point because boiling point is a bulk property that involves interactions between many molecules. It is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure.
Which water freezes first boiling water cold water or room temperature.?
Cold water would freeze the fastest because freezing is a physical change brought on by temperature change, and the temperature of cold water is closer to freezing temperature than boiling or room temperature water. Therefore, it would take less time to reach freezing temperature.
What is the trend of temperature of boiling water would be if it were graphed using a line graph?
Boiling water would have a horizontal line graph if time was on the horizontal axis and temperature was on the vertical axis.Water will not change temperature as it changes state - from a liquid to a gas or from a solid to a water.Water can change temperature if it is solid or liquid or gas.
What happens to the temperature of boiling water when heat is added to the boiling water?
If you add energy to a boiling liquid, it will just boil faster, but the temperature will remain the same, at the boiling point. All the energy goes into phase change, not heating.
Which would mostlikely be the temperature of boiling water?
373K
How could you change the boiling and freezing temperature of water?
If you want to limit yourself to water only, you could change the pressure. That would greatly change the boiling point and slightly change the freezing point. If you don't care about limiting yourself to pure water, you can dissolve a salt or other substance in the water to lower the freezing point and raising the boiling point.
Why would most likely be the temperature of boiling water?
Which is most likely be the temperature of boiling water? 100oC is the boiling point of pure water - when water is boiling, it stays at a constant temperature until all of it is evaporated.
What would happen to boiling water if an impurity is added?
Adding an impurity to boiling water, such as salt, sugar, or other substances, can change the boiling point of the water. The impurity will raise the boiling point of the water, meaning it will need to reach a higher temperature to boil. This effect is known as boiling point elevation.
What element would melt in boiling water?
all the elements that has low boiling point than of the water.
Is boiling water on a stove chemical or physical change?
This involves a change of state of the water. Before, during, and after the boiling, it remains water. So, since the substance doesn't change its character, the boiling of water is a physical change.
Why is temperature of boiling water cannot be measured using an alcohol thermometer?
Alcohol thermometers are not suitable for measuring the temperature of boiling water because alcohol has a lower boiling point than water. The alcohol inside the thermometer would evaporate before reaching the temperature of boiling water, therefore providing an inaccurate reading.
Can a material gain energy and not change temperature?
Yes, a material can gain energy without changing temperature through a process called phase change, where the energy is used to change the state of the material (solid, liquid, gas) rather than increase its temperature. Examples include melting ice or boiling water.
Which took more time heating the water from room temperature to boiling point or boiling all the water away?
Boiling all the water away would take more time than heating the water from room temperature to boiling point. This is because during the boiling process, the water needs to be heated from boiling point to overcome the latent heat of vaporization to turn it into steam, which takes more time compared to heating it from room temperature to boiling point.
