How does temperature affect viscosity of motor oil?

Yes. If the temperature changes enough, the viscosity of oil will change, too. Oil is designed to resist changes in viscosity with temperature changes, at least to a degree. But if the change (either hotter or colder) is extreme, then the viscocity will most certainly change. And, as you'd expect, as it gets hotter, the viscosity of oil decreases (it get thinner), and as it gets colder, the viscosity of oil increases (it gets thicker).

Is the statement the bigger hey are the harder they fall true?

The statement "the bigger they are, the harder they fall" suggests that individuals or entities that are powerful or successful are more likely to experience a significant downfall. This is often seen as a warning against becoming too overconfident or complacent in one's achievements. While there can be instances where this proves to be true, it is not a universal rule that applies in every situation.

How can a mirror reflect light and is it possible to have a reflection in pitch black darkness?

A mirror reflects light by causing photons to bounce off its smooth surface at an angle equal to the angle of incidence. In pitch black darkness, where there is no light to reflect off a surface, it is not possible to have a reflection in the traditional sense. However, some surfaces can reflect a limited amount of light even in very low light conditions due to their material properties.

Is clay an example of amorphous solid?

No. An amorphous solid is a solid in which there is no long-range order of the positions of the atoms. Solids in which there is long-range atomic order are called crystalline solids or morphous. Salt is a solid with long-range atomic order and hence is morphous in nature.

Some examples of amorphous solids are common window glass, many polymers (such as polystyrene) are amorphous, and even foods such as cotton candy.

Can lens be made with water?

Well, the water would normally flow away, so you would either have to use a container (plastic or glass), or freeze the water.

Any real outdoors-man knows that you can make a lens out of water and a plastic bag. In fact, if you are really good at this you can start fires using this type of lens to focus sunlight.

What is the principle of the electron diffractionof graphite?

The principle of electron diffraction of graphite involves using a beam of electrons to interact with the crystal lattice of graphite. When the electrons hit the lattice, they diffract, producing a pattern that can be used to determine the crystal structure of graphite. By analyzing the diffraction pattern, information about the arrangement of carbon atoms in the graphite crystal lattice can be obtained.

Why do some solid substances do not return to their original size or shape when distorted by an outside force?

Some solid substances exhibit plastic deformation, where the molecular structure changes permanently when subjected to an outside force. This change can be due to dislocation movements, breaking of chemical bonds, or the realignment of atoms within the crystal lattice, preventing the material from returning to its original size or shape after deformation.

What is the properties of isotropic material?

Isotropic materials have the same mechanical properties in all directions. This means they exhibit identical responses to stress or strain, regardless of the direction in which they are applied. Isotropic materials are characterized by having uniformity and symmetry in their properties.

Which property of light ray does not change in refraction?

The frequency of a light ray does not change when it undergoes refraction. The wavelength and speed of light can change, but the frequency remains constant. This is because frequency is a characteristic of the light source, not of the medium through which light is traveling.

How does heat travels if there is air?

Heat can travel through air by conduction, convection, and thermal radiation. In conduction, heat is transferred through direct contact between molecules. In convection, heat is carried by the movement of air currents. Thermal radiation is the transfer of heat in the form of electromagnetic waves.

Is gold viscous?

At normal temperatures and pressures, gold is a sold and the concept of viscosity is not applicable to it.

Once it is hot enough to melt, the liquid form does have a measurable viscosity. As with all other liquids the higher the temperature, the less viscous it becomes.

Does thrust help a ship to float?

No, thrust does not help a ship float. A ship floats due to the principle of buoyancy, which is a result of the displacement of water by the ship's hull. Thrust is used to propel the ship through the water.

How can lower air pressure make liquids evaporate faster?

You can explain this in a number of different ways.

A high air pressure promotes the return of evaporated molecules to return to the liquid state, so a low air pressure is more amenable to the existence of evaporated molecules in the gaseous state.

Is lead a crystalline solid or amorphous solid?

as with all metals, lead is a polycrystalline solid.

What is the name of the path followed by water drop?

The water drop goes stright down, but it gets slightly squashed during the way down, like a hamburger shape.

Why does a piece of water melon stay cool for a longer time than sandwiches when both of them are taken out from the refrigerator on a hot day?

Well, a watermelon has a much higher specific heat than a sandwich. This is because Water (H2O) has an unusually high specific heat, and the watermelon contains much more water than the sandwich. The higher the specific heat of an object the more calories it takes to increase its temperature, this applies to cooling as well. So, a watermelon will take longer to get cold, but it will stay cool longer.

Another factor is the surface area in comparison to each objects mass. The Watermelon, in a sense, insulates the temperature of the cooler.

Which term is defined as process by which a changes state from solid to liquid?

The term defined as the process by which a substance changes from a solid to a liquid is "melting." It involves adding heat to a solid material to increase its kinetic energy and break the intermolecular forces holding its particles in a fixed position, resulting in the transition to a liquid state.

How do you find kinetic friction without the coefficient?

You can find the kinetic friction force by measuring the normal force acting on the object and the net force experienced by the object when it is in motion. By applying Newton's second law (F = ma), where a is the acceleration of the object, you can calculate the kinetic friction force without knowing the coefficient.

What is crystal potential?

Crystal potential refers to the energy associated with the arrangement of atoms in a crystal lattice. It includes contributions from various interactions such as electrostatic, van der Waals, and repulsive forces between atoms. The crystal potential determines the stability and properties of a crystal structure.

What is the wavelength of a signal that travels in air with a period equals .0000025 sec What is the signal's frequency?

Both sound and electromagnetic waves can travel in air, and you haven't said

which one we're talking about. So it's not possible to calculate the wavelength,

because we don't know the speed.

Frequency = 1/period = 1/2.5 x 10-6 = 400 KHz

What happens when you piss into the wind?

Your own urine hits you in face. Usually this is a thought experiment, capable of being figured out by those who consider it. Only a small fraction of the population actually have to be told about it; fewer still who actually need to perform the experiment.

What is the viscosity of a dilute dispersion of silica particles in water?

The viscosity of a dilute dispersion of silica particles in water would depend on factors such as the particle size, concentration, and surface chemistry of the silica particles. In general, the addition of solid particles to a liquid can increase viscosity due to the particles disrupting the flow of the liquid. The viscosity can be measured experimentally using viscometers.

How does conduction take place in graphite?

Because there free electrons are present in conduction shell of graphite hence this electrons transfer charge from one place to another place in graphite crystal, & makes it conductive.Ok bhAI

What is the difference between plastic wrap and shrink wrap?

Plastic wrap is a thin, flexible material used for covering food containers or for wrapping food items to keep them fresh. Shrink wrap is a thicker, more rigid material used for wrapping and protecting items for shipping or storage. Shrink wrap shrinks when heat is applied, conforming tightly to the shape of the object.
