What Are Lubricants?
What are lubricants? Definition. Lubricant is a substance which is used to control (more often to reduce) friction and wear of the surfaces in a contact of the bodies in relative motion . Depending on its nature, lubricants are also used to eliminate heat and wear debris, supply additives into the contact, transmit power, protect, seal.
What are lubricants for Class 8?
A substance that is introduced between two surfaces in contact, to reduce friction, is called a lubricant. Fluid friction can be minimized by giving suitable shapes to the objects moving in the fluids.
What is a lubricant short answer?
Lubricant is a substance used to reduce friction between surfaces in contact which reduces heat generated when the surfaces move. The property of reducing friction bisetween two particles is known as lubricity. Example: oil, grease. musashixjubeio0 and 22 more users found this answer helpful.
What are lubricants and its types?
There are three different types of lubrication: boundary, mixed and full film. Each type is different, but they all rely on a lubricant and the additives within the oils to protect against wear. Full-film lubrication can be broken down into two forms: hydrodynamic and elastohydrodynamic.
What does lube do for a woman?
Lube reduces friction, so lessens your risk of injury during sex. And if you're using condoms, lube also makes it less likely that it'll break or fall off, therefore increasing your protection against STIs including HIV.

Is Vaseline good for lube?
Although Vaseline may work as a sexual lubricant, it can damage latex condoms and increase the risk of infection and unintended pregnancy. Vaseline does not get sticky or dry out, which — in theory — also makes it a good lubricant option. However, it is not advisable to use Vaseline as a sexual lubricant.
What are lubricants in science?
A lubricant is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. The property of reducing friction is known as lubricity. In addition to industrial applications, lubricants are used for many other purposes.
What is fluid friction Class 8?
There is a friction whenever an object moves through a fluid.It is called fluid friction. When an object moves through water, it pushes the water out of the way and the water pushes back on the object. This push of water on the moving object creates fiction which tends to slow down the moving object.
What is the example of lubricant?
Common examples of internal lubricants include fatty alcohols, esters (low esterification), and EVA wax. External lubricants provide metal release and help reduce process temperature. Common examples of external lubricants include PE waxes, paraffin, metal soaps, esters (high esterification), amides, and fatty acids.
What is a lubricant for kids?
A lubricant is a substance used to reduce friction between moving surfaces. The property of reducing friction is known as lubricity (slipperiness).
What is the main purpose of the lubricant?
The primary purpose of lubrication is to reduce wear and heat between contacting surfaces in relative motion.

How do lubricants work?
Lubricants aim at reducing friction between moving pieces and at reducing passive resistance of the stationary parts. They are produced by refining heavy fractions of crude oil (remaining crude oil parts after refining hydrocarbons such as gas, fuel oil or kerosene).
Is it OK to use olive oil as lube?
Although olive oil has other benefits for health, people should avoid using it as a sexual lubricant. Olive oil has the potential to dissolve latex condoms, which can increase the risk of infection and unintended pregnancy. Due to this, it is not advisable to use olive oil as a sexual lubricant.
Can I use coconut oil as lube?
According to a 2014 study, coconut oil is clinically proven for safe and effective use as a moisturizer. Its moisturizing properties may make the product an effective lube and allow for longer-lasting intercourse. For women going through menopause, coconut oil may be especially helpful.
Is water an OK lube?
"It's not well-tolerated by all people either, so test it on your skin before using." Again, a water-based lube is generally best to use instead. For condoms: It's okay to use with non-latex options, it's definitely not recommended for conventional latex.
What are liquid lubricants?
Liquid lubricants are liquids that separate and reduce friction between two moving surfaces and decrease wear and tear. The properties of good liquid lubricants are as follows. Properties of oiliness. Appropriate viscosity and should not change appreciably with a change in temperature.
What is lubricant made of?
The most common industrial lubricants primarily consist of a base oil and are either mineral-based, synthetic, or vegetable-based. Additives are also added to the base oil to optimize the properties of the lubricant. Another form of lubricant, grease, is made by combining a base oil with a thickening agent.
What is a fluid friction?
Fluid friction is a force that restricts the movement either within itself or of another medium moving through the liquid. It describes the friction between the layers of the viscous liquid that moves relative to each other. The internal resistance to flow is termed as viscosity.
What is fluid friction Class 11?
When a body moves through a fluid which may be liquid or air, there is interaction between molecules of fluid and the body which tries to resist the motion of the body through that fluid. This is called fluid friction.
What are fluids Class 9?
Fluids : Fluids are the substances which have tendency to flow. A liquid is a fluid form of matter which occupies the space of the container.
