Why did heating the water affect the surface tension?
Surface tension is lower at higher temperatures.
What is the effect of detergent on the surface tension?
Detergent reduces the surface tension of water by breaking the hydrogen bonds between water molecules. This allows the water to spread and penetrate surfaces more easily, making it an effective cleaning agent.
Why does kerosene have less surface tension?
Kerosene has less surface tension than water because its molecules are less polar and can't form hydrogen bonds as easily as water molecules. This results in weaker intermolecular forces between kerosene molecules at the surface, leading to lower surface tension.
How would the surface tension of water be affected if water was a less polar molecule?
If water were a less polar molecule, its surface tension would likely decrease. Surface tension in water is primarily due to the hydrogen bonds formed between water molecules, which are a result of water's polarity. A less polar molecule would not form as strong hydrogen bonds, leading to weaker surface tension.
Does density of water increase or decrease the surface tension of water?
The surface tension of water is due to cohesive forces between water molecules. Density does not directly affect surface tension, but impurities or additives can alter it. Essentially, the surface tension of water remains constant regardless of its density.
Does gasoline have a low surface tension?
yes it is lower than the surface tension of water
What are compounds that lower the surface tension of water?
Unit cells
Surface tension of water at different temperatures?
Surface tension of water decreases as temperature increases. At lower temperatures, water molecules are more closely packed, leading to stronger intermolecular forces and higher surface tension. As temperature rises, water molecules gain kinetic energy and move more freely, causing weaker intermolecuar attractions and lower surface tension.
What causes detergent to lower the surface tension of water?
Some mood music.
Why did heating the water affect the surface tension?
Surface tension is lower at higher temperatures.
What is the effect of sodium chloride on the surface tension of water?
The surface tension of water is increased for salted water.Sodium chloride increase the surface tension of water.
How does soap effects the surface tension if water?
Soap reduces the surface tension of water by disrupting the hydrogen bonds between water molecules. This allows the water to spread out more easily and penetrate surfaces to lift away dirt and oil.
Is acetone thicker than water?
No, acetone is thinner than water. Acetone is a volatile liquid solvent with a lower viscosity compared to water.
What is the effect of detergent on the surface tension?
Detergent reduces the surface tension of water by breaking the hydrogen bonds between water molecules. This allows the water to spread and penetrate surfaces more easily, making it an effective cleaning agent.
Why does kerosene have less surface tension?
Kerosene has less surface tension than water because its molecules are less polar and can't form hydrogen bonds as easily as water molecules. This results in weaker intermolecular forces between kerosene molecules at the surface, leading to lower surface tension.
How does sodium carbonate affect the surface tension of water?
Sodium carbonate decreases the surface tension of water by acting as a surfactant. It disrupts the hydrogen bonding between water molecules, allowing them to spread out more easily across a surface. This results in a reduction of the cohesive forces at the surface of the water, leading to a lower surface tension.
What makes a needle to float in water?
A needle can float on water due to surface tension. When the needle is carefully placed on the surface of the water, its weight is not enough to break the surface tension created by the water molecules, causing it to float.
