What property does grease have that repels water?
Grease is hydrophobic, meaning it repels water due to its non-polar nature. The non-polar molecules in grease are not attracted to water molecules, causing them to be pushed away, leading to the repulsion of water.
Explain why grease on clothing will not come out with cold water?
Grease on clothing will not come out with cold water because grease is a type of oil that solidifies and sticks to fabric fibers. Cold water is not hot enough to melt the grease and break it up from the fabric, making it difficult to remove. Using hot water, along with detergent or a grease-fighting stain remover, can help dissolve the grease and lift it from the fabric.
Why is grease and oil insoluble in water?
Grease and oil are nonpolar substances, while water is a polar substance. Nonpolar substances do not mix with polar substances due to their different molecular structures. This causes grease and oil to be insoluble in water.
Why does hot grease pop when mixed with water?
It pops because the grease's temperature is hotter then the water or food supply that your are examining by the grease being really hot the cooler temperature of the substance causes the grease to pop and crackle
Matter can exist in only three phases called what?
The tree phases of a matter are called Solid, liquid and gas. For example, water is present in the form of Ice, liquid water and water-vapour or steam.
Stones,dust and grease present in water are called?
Evaporation
What are stone and grease in water called?
When stones and grease are present in water, they can form a substance known as "scum." Scum is a layer of impurities that float on the surface of the water due to their differing densities. The stones and grease do not mix with the water but instead combine to create this film-like layer, which can be unsightly and potentially harmful to aquatic ecosystems.
Why does grease splatter?
If there is water contained in a "grease bubble", as the grease is heated, the water evapourates and expands, causing the grease bubble to burst.
Why is it difficult to clean grease stains on clothing with water alone?
because water is dense than grease, is stays separate from the grease. however, when a detergent is applied, it acts as an emulsifier, allowing the grease to mix with the water and come of the clothing.
How does Trisodium phosphate work to remove grease?
Trisodium phosphate works to remove grease by breaking down the grease molecules through a process called saponification. This causes the grease to become water-soluble and easier to wash away. Additionally, trisodium phosphate is highly alkaline, which helps to cut through and dissolve the grease.
What will grease do if water is put on a grease fire?
The grease will keep burning but the water will sink below the surface, flash to steam from the heat and the expansion will blow the burning grease out like an explosion.
Why would water not be effective in cleaning up a grease spill?
Water is not effective in cleaning up grease spills because grease is nonpolar and does not mix with water. Water molecules are polar and cannot break down the nonpolar grease molecules. This causes the grease to float on top of the water, making it difficult to remove.
What property does grease have that repels water?
Grease is hydrophobic, meaning it repels water due to its non-polar nature. The non-polar molecules in grease are not attracted to water molecules, causing them to be pushed away, leading to the repulsion of water.
How much dawn dish soap do you need for grease?
It depends on what kind of grease, how much grease, how water is used, and the temperature of the water among other factors.

Is the printmaking process that is based on the observation that grease and water will not mix?
Yes, the printmaking process based on the observation that grease and water will not mix is called lithography. In lithography, an image is drawn with a grease-based medium on a flat stone or metal plate. When the plate is treated with a chemical solution, the grease repels water, allowing ink to adhere only to the drawn areas, which can then be transferred onto paper. This method allows for detailed and nuanced prints.
