The leaf was placed in alcohol wafter being placed in the boiling water to extract the green pigment from the leaf.
Alcohol thermometers typically have a lower maximum temperature range compared to mercury thermometers, making them unsuitable for measuring the high boiling point of water. Alcohol thermometers may not accurately measure temperatures above their boiling point, which is lower than water's boiling point.
it is some type of alcohol did a distillation lab on it today
Fractional distillation is appropriate to separate ethanol and water because they have different boiling points: ethanol at 78.4°C and water at 100°C. During fractional distillation, the mixture is heated to a temperature in between these boiling points, allowing the ethanol to vaporize but not the water. The vapor is then condensed and collected, resulting in separate ethanol and water fractions.
steam hits a cold surface makes a liquid. also known as condensation
The boiling point of water is unique because it occurs at a specific temperature of 100 degrees Celsius (212 degrees Fahrenheit) at sea level, under standard atmospheric pressure. This specific boiling point is a result of the balance between the forces holding water molecules together and the energy needed to break those forces and transition to a gaseous state.
it has to be placed in alcohol first because lipids are soluble in alcohol but not in water.
Water has a higher boiling point that alcohol (ethanol). The main reason for this is because water has stronger intermolecular forces holding the molecules together.
When you steam the lobster, it is placed in a basket above a pot of boiling water. When you are boiling the lobster, it is placed directly into the boiling water.
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.
Alcohol thermometers typically have a lower maximum temperature range compared to mercury thermometers, making them unsuitable for measuring the high boiling point of water. Alcohol thermometers may not accurately measure temperatures above their boiling point, which is lower than water's boiling point.
The total amount of alcohol content will not diminish. However as the volume of liquid is increased then the alcohol percentage by volume will decrease. Some may also evaporate with the hot water but it would be a very small amount.
The boiling point of a mixture of alcohol and water depends on the ratio of the two substances. For example, a solution of 20% alcohol and 80% water will have a boiling point higher than either pure alcohol or water. The boiling point elevation is due to the interactions between the alcohol and water molecules.
Distillation! Water and alcohol have different boiling points; one is lower than the other. Heat the mixture up until it one of the two boils away. In the case of alcohol and water, alcohol has the lower boiling point. Heat the mixture to just above the boiling point of alcohol but below the boiling point of water and voila!- you've separated the mixture.
Sure! It's called distillation and it's done all the time, especially in Kentucky. Alcohol's boiling point is lower than water's is. If you heat an alcohol-water solution to alcohol's boiling point, the alcohol will boil off leaving the water behind.
The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.
it cools it
Alcohol has a lower boiling point than water. Naturally the alcohol evaporates leaving the flavanoids and the water. If you boil 100 % alcohol, then it would act like plain water. It will boil until it all evaporates.
