It would need a higher specific heat capacity and/or a higher latent heat of fusion. This ensures that more thermal energy is absorbed before it can no longer wick away thermal energy from the system.
The criterion "better" is not well defined. A coolant can cool faster, or to a lower temperature, or be more affordable or less toxic than another coolant, or more environmentally friendly. Freon is better than ammonia by some criteria, and worse by others (it is less toxic, but more environmentally harmful). Liquid nitrogen cools things faster and to a lower temperature than ice does, but you might not want to put it in your drink (which would immediately freeze and become undrinkable). Water frozen into ice is a perfect coolant for some purposes, such as keeping my glass of ice tea cold. I would use no other coolant for that purpose.
If a substance is cooled and solidified rapidly, generally amorphous material is obtained instead of crystals. In order to obtain good quality crystals, if is better that the substance solidifies slowly
No, marble does not attract to a magnet. Marble is primarily composed of calcium carbonate, which is a non-magnetic material. In order for a material to be attracted to a magnet, it needs to have magnetic properties, such as containing iron, nickel, or cobalt. Since marble lacks these magnetic elements, it will not be attracted to a magnet.
No, you cannot determine the chemical properties of a can just by looking at a picture. Different metals like tin and aluminum have distinct physical properties, but to identify the exact metal used in a can, you would need to perform a chemical analysis or consult the manufacturer's specifications.

You need to observe at least two sets of properties to classify a material as a heterogeneous mixture. This is because a heterogeneous mixture is a combination of different substances that can be distinguished by their properties, such as size, color, and phase. By observing multiple sets of properties, you can confirm that the mixture is not uniform in composition.
To classify a material as a homogeneous mixture, you typically need to observe at least two sets of properties. These properties should indicate that the components of the mixture are uniformly distributed and that there are no visible differences between different parts of the mixture.
You cooling system requires coolant in order to keep working properly, if you are wondering why your room is still hot even though you have the AC on; it is because your air conditioner is out of coolant. Just call your local heating and cooling specialist.
The phase transition in this material is of second order.
this is normal,because the coolant temp sensor is supposed to be in direct contact with the cooling fluid in order to read its temperature
Nematic order is important in the study of liquid crystals because it describes the alignment of molecules in a specific direction, which affects the physical properties of the material. This alignment allows liquid crystals to exhibit unique optical and electrical properties, making them useful in various applications such as displays and sensors.
A fourth-order tensor in physics and engineering is a mathematical object that represents relationships between two sets of vectors. It has properties such as symmetry and transformation rules. In applications, fourth-order tensors are used in areas like continuum mechanics, material science, and fluid dynamics to describe complex physical phenomena with multiple directions and components.

An isotropic material is one which looks the same in every direction. We cannot define any special direction using the material properties. In other words, none of the properties depend the orientation; it is perfectly rotationally symmetric. Note that in order to be isotropic the material must be homogenous on the length scale of interest, ie the same at every point in the material. For instance, rubber is a very isotropic material. Take a rubber ball, and it will feel the same and bounce the same however you rotate it. On the other hand, wood is an anisotropic material: hit it with an axe and it will take more force to break of you are cutting across the grain than along it. (Remember we're thinking about the material rather than the shape of the object.)
An oil coolant?æ hose is a tube or pipe that allows engine oil to circulate via the radiator in order to cool down. Without an oil coolant hose, oil will get to hot to operate efficiently.
The advantages are that students are learning more material in order to be better prepared and more educated. Disadvantages are that there is more material to cover in the same amount of time and students may fall behind.
