Having an engine, body, chassis and four wheels is what is specific to a car.
The late Latin word specifĭcus came into Spanish as specific . The term refers to that which is distinctive or characteristic of something .
Differentiating feature
The specificity of an element is what differentiates it from others , or what allows it to be included in a set with other elements with similar properties . It can be said that what is specific about a car is that it is a vehicle with an engine, body, chassis and four wheels, for example. A vehicle with two wheels is therefore not a car.
precise or concrete
The notion of specific also refers to what is precise or concrete : “The singer gave specific instructions about how he wants his hotel room prepared,” “To allocate subsidies, the government studies compliance with specific requirements by those who apply.” help” , “I feel bad, but nothing specific hurts me, but rather I have a general malaise…” .
Suppose that, in an industrial plant, a certain machine stops working. After a technical review, specialists come to the conclusion that a certain part needs to be replaced to repair it. Therefore, you must obtain a specific part that is appropriate for said machine, not just any spare part.
Specific magnitude
A specific magnitude , on the other hand, refers to a unit of mass . This is the value that the magnitude in question adopts according to each unit of mass of the system of units that is used.
This concept belongs to the field of physics, and in this framework we find the following names: specific energy, specific heat and specific volume. It should be noted that it is not correct to speak of specific weight , although it was used for a long time and continues to be part of some dictionaries of our language; The name that is accepted today is weight per unit of mass , that is, newtons per kilogram , and we should speak of weight density .
Specific energy
Specific energy , in this framework, is the energy per unit of mass, expressed in joules per kilogram. The specific heat , meanwhile, is the amount of heat required to increase the temperature of the unit of mass by 1 K.
On the other hand, there is a homonymous concept that is used in the field of hydraulics and that refers to the energy per weight of water in a given part of a channel, in reference to its bottom. To calculate it, the following equation is used: d * cos(θ) + (V 2 α) / (2 * g) , where d is the depth, θ is the angle of the slope and the horizontal, α is the Coriolis coefficient and g is the gravitational acceleration.
specific heat
This concept is also known as specific heat capacity or specific heat capacity . This is the magnitude of heat that must be delivered to the unit mass of a thermodynamic system or a given substance so that its temperature increases by one unit. The measurement of specific heat is carried out on various scales.
In hydraulics, the specific energy is the energy existing per weight of water in a part of a channel, in reference to its bottom.
Specific volume
This is the name given to the volume that a material occupies per unit of mass. The inverse concept is called density , so that there is no dependence on the amount of the sample used when performing the calculation. This makes it part of the so-called intensive properties, along with boiling point, color, gloss, melting point and hardness, among others.
With respect to its equation , the specific volume is calculated with the ratio of the volume over the mass, in an equality with 1 over the density: V/m = 1/ρ .
