What else can I help you with?
Is kerosene and water a substance or a mixture?
It is a mixture of hydrocarbons. Kerosene is a hydrocarbon extracted from petroleum through fractional distillation. It is a mixture of hydrocarbons with different number of carbon atoms(10-14). The boiling point RANGE of kerosene is 170-250 degrees Celsius.
What is the name of the temperature at which a mixture freeze?
The temperature at which a mixture freezes is called the freezing point. For instance, water freezes at 32 degrees F. at sea level.
Can solid and a liquid form a mixture?
Water and crushed ice form a freezing point mixture.
How antifreeze affects the freezing point of water?
It lowers the temperature where the mixture will freeze
What is the freezing point of detergent?
The freezing point of detergent can vary depending on its composition. Generally, detergents are a mixture of chemicals and water, which lowers the freezing point compared to pure water. It typically ranges from -10°C to -20°C.
Is the freezing point of a mixture of water and salt higher lower or the same of pure water or none?
lower
What if ice cubes are put in kerosene?
If ice cubes are put in kerosene, the ice will melt due to the higher temperature of the kerosene. Kerosene has a lower freezing point than water, so it will not freeze the water in the ice cubes. The ice will eventually melt and mix with the kerosene, but they will not chemically react with each other.
If a student wishes to test the hypothesis that adding antifreeze to water lowers the freezing point of water. What would be the dependent (responding) variable?
The dependent (responding) variable in this experiment would be the freezing point of the water-antifreeze mixture. This is because the freezing point is what the student measures and observes in response to varying amounts of antifreeze added to the water. Changes in the freezing point will indicate how the addition of antifreeze affects the freezing characteristics of the water.
What is the lab equipment for separating kerosene water mixture?
The lab equipment commonly used for separating a kerosene-water mixture is a separating funnel. The mixture is poured into the funnel, and due to the immiscibility of kerosene and water, they separate into distinct layers with the denser water sinking to the bottom and the lighter kerosene floating on top. The tap at the bottom of the funnel can then be opened to drain off the water, allowing for the collection of the kerosene.
If you mix water and rubbing alcohol will it freeze?
Well, isn't that a happy little question! When you mix water and rubbing alcohol together, the freezing point of the solution will be lower than that of water alone. This means it will be harder for the mixture to freeze compared to plain water. Just like creating a beautiful painting, experimenting with different materials can lead to interesting results!
What is the freezing point of mixture alkohol and water?
The freezing point of a mixture of alcohol and water will depend on the specific types and amounts of alcohol and water present. In general, adding alcohol to water will lower the freezing point of the mixture compared to pure water. This is because alcohol disrupts the formation of ice crystals in the solution.
What is freezing mixture?
A freezing mixture is a combination of substances that, when mixed together, can lower the temperature significantly, often below the freezing point of water. Commonly, it consists of ice and salt, where the salt lowers the freezing point of the ice, allowing the mixture to reach temperatures suitable for freezing or chilling other substances. This technique is frequently used in laboratories and culinary applications, such as making ice cream.
