What else can I help you with?
Is it correct to say that the addition of salts to water will always increase the surface tension of water?
Yes, the addition of salts to water typically increases the surface tension of water. This is because the salts disrupt the hydrogen bonding within water molecules, leading to stronger water-water interactions at the surface, which increases surface tension.
Does surface tension change when bleach is added to it?
Yes, surface tension can change when bleach is added to water. Bleach is a surfactant that can reduce the surface tension of water by disrupting the hydrogen bonding between water molecules. This can lead to a decrease in surface tension and cause water to spread more easily.
What surface tension of an aqueous solution is generated by the presence?
The surface tension of an aqueous solution is influenced by the presence of solutes, which can either increase or decrease it depending on their nature. For example, surfactants reduce surface tension by disrupting cohesive interactions between water molecules, leading to a lower surface tension. Conversely, some solutes, like salts, can increase surface tension by enhancing the cohesive forces amongst water molecules. Overall, the specific impact on surface tension depends on the type and concentration of the solute present.
What state of matter does not change in volume but has surface tension?
liguid
Does lungs excrete salts from its surface?
Lungs can not and does not excrete salts from its surface.
When you dissolve something in water does that change its capillary action or surface tension?
yes
Does fresh water have more surface tension than salt water?
Cold water has stronger (better) surface tension.Surface tension is dependent on temperature. For that reason, when a value is given for the surface tension of an interface, temperature must be explicitly stated. The general trend is that surface tension decreases with the increase of temperature, reaching a value of 0 at the critical temperature.From: http://en.wikipedia.org/wiki/Surface_tensionAdded emphasis for readability.dfsfdytrhjtkjkjh
Why the change in surface tension is much less when sodium chloride is added to water in place of an equivalent amount of ethanol?
Sodium chloride is an ionic compound that dissociates into ions when dissolved in water, causing no significant change in the cohesive forces between water molecules. Ethanol, on the other hand, is a covalent compound that disrupts the hydrogen bonding between water molecules, leading to a greater change in surface tension.
What is the effect of pH on surface tension?
Surface tension typically decreases as the pH of a solution becomes more acidic or basic. This is due to changes in the concentration of ions at the liquid-air interface, which affects the attractive forces between molecules. In general, a change in pH can disrupt the hydrogen bonding between water molecules, leading to a decrease in surface tension.
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.
Which of the following is not a consequence of force A Weight B Surface tension C Gravitational pull D Magnetic force E Electrical force?
Surface tension is not a consequence of force. Surface tension is a property of liquids that arises due to intermolecular forces acting at the surface of the liquid. It is not a force acting on an object.
Which describes surface tension of water when detergent is added A increases B decreases C becomes zero D shows no change?
B) Decreases. When detergent is added to water, it reduces the surface tension by disrupting the hydrogen bonding between water molecules. This causes the water molecules to spread out more evenly across the surface, lowering the surface tension.
