What are surfactants?
A substance that tends to reduce the surface tension of a liquid in which it is dissolved.
What is the name for liquid that reduce friction?
The liquid that reduces friction is called a lubricant. Lubricants are used to minimize the friction and wear between moving surfaces by forming a film that separates them.
What is an example of viscous Friction?
An example of viscous friction is the resistance experienced when moving an object through a fluid, such as air or water. This type of friction is proportional to the velocity of the object and the viscosity of the fluid it is moving through. An example could be stirring a thick liquid like honey, where the resistance increases as the speed of stirring increases.
How much surfactant is in a bar of soap?
A surfactant is a substance that, when mixed with a liquid, reduces its surface tension. There are usually two or more surfactants in a bar of soap.
What reduces the friction between the lungs and the walls of the thorax?
The pleural fluid reduces the friction between the lungs and the walls of the thorax by lubricating the pleural surfaces. This fluid allows the lungs to move smoothly during respiration without causing friction or resistance.
What is internal friction in liquid?
Internal friction in a liquid refers to the resistance encountered by the liquid molecules as they flow past each other. It is a measure of how easily the liquid can respond to external forces and deformations. Internal friction affects the viscosity of the liquid, with higher internal friction leading to higher viscosity.
Why must special care be taken when we walk on wet floor?
Whatever liquid on the floor acts as a lubricant and reduces the friction between the floor surface and feet, and butt if one is clumsy.
What is a liquid is a substance?
A liquid is a substance or a mixture of substances in solution.
What causes the particles of a substance to condense?
Particles of a substance condense due to a decrease in temperature or an increase in pressure, which reduces the kinetic energy of the particles. As temperature drops, particles move slower and lose energy, allowing intermolecular forces to pull them closer together. This leads to a transition from a gas to a liquid or from a liquid to a solid, depending on the substance and conditions.
When a substance changes from a liquid to a gas energy is . When a substance changes from a gas to a liquid energy is .?
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
Can a liquid substance diffused in a liquid substance?
yes water is liquid it is known as the universal solvent
What is a non-liquid substance?
A non-liquid substance is a material that is not in a liquid state, such as a solid or a gas.
