What is Heat and Temperature? What are the Properties of Heat and Temperature?
Temperature : It is a value that expresses the average motion (kinetic) energy of one of the particles that make up a substance. Temperature is not energy. It is measured with a thermometer. Heat : It is the name of the energy that is exchanged between two substances with different temperatures.
Heat is the name of the energy that is exchanged between substances with different temperatures. Regardless of whether the substance is in the solid, liquid, or gas phase, heat moves from the higher-energy substance to the lower-energy substance. This is called heat exchange. The unit of heat energy is joule ( j ) or calorie (cal). A calorie is the amount of energy required to increase the temperature of 1 gram of water by 1°C at atmospheric pressure, and 1 calorie is equal to 4.18 joules. Temperature, on the other hand, refers to the zero degree, which is the freezing point of water, as a sensible magnitude, and the temperature of the substance is read from the temperature scale on the thermometer. The temperature of an object depends on the vibrational rate of its molecules. The faster its molecules vibrate, the hotter the object, and the slower it vibrates, the colder the object. The heat, which tends to pass from the side where the temperature is high to the side where it is low, encounters a resistance during this transition depending on the thermal conductivity coefficients and thickness of the materials between the spaces. In the most general senseThermal insulation applications , namely sheathing , is a resistance that reduces heat transfer. Heat transfer occurs in 3 ways by conduction, convection and heating .
In addition to being the most qualified of the service class that our company will offer you, as we mentioned, it will be produced with the materials that are the exact equivalent of your needs and the optimum insulation prices will be created for you.
The spread of heat by conduction occurs in solids. The molecule that receives the heat energy of any solid object transfers some of this energy to the molecules to which it is attached. Heat transfer continues with the transfer of this energy by molecules to which heat is transferred to other molecules to which they are attached. Another name for this type of heat conduction is " Conduction ". Heat conduction is a distinctive feature for solids, especially materials .
transport; motion is the form of heat energy transfer by movable molecules in liquid and gaseous state. The volume of the heated substance increases and the density decreases. Density changes occur due to the displacement of molecules in a gas or liquid mass. With this movement of molecules, heat energy changes coordinates and is carried from one place to another. This heat convection is from the region where the energy is high to the region where it is low and shows the convection feature of the substance whether it is in the liquid or gaseous state. The movement of air molecules associated with a heater by rising and their displacement with cold air molecules in higher coordinates, the cold air molecules taking heat energy by hitting the heater surface and moving upwards can be given as examples of energy transfer by convection.
The propagation or transmission of energy in the form of electromagnetic waves or particles is called radiation or thermal radiation. Objects that store heat energy emit thermal radiation by emitting most electrified Romanmagnetic waves, such as ultraviolet, infrared, microwaves and radio waves. Matter can transfer the heat energy it carries to another substance by radiating energy.
Any object with a temperature above 0 Kelvin or -273°C emits energy by radiation. There is no need for any other random substance such as solid-liquid or gas for heat transfer during radiation. Even in a vacuum, radiation transfer is possible. The effects of the sun's rays on the earth or the heat energy emitted by a random light source can be examples of this state.
It will be possible to provide comfort in your buildings with thermal insulation materials of varying thickness and densities . In addition to the sheathing processes, the trick is to make thermal insulation, which can be applied later on , and you can have thermal insulation programs done by using the best sheathing materials for your needs . Materials preferred for sound insulation allow the application of " heat insulation " by applying them later to the structures. What is sheathing? You can also use our article.
" Rock wool jacketing which can be produced in the form of mattresses, plates (plates), pipes and bulk with exterior coating materials , " sheathing types " used for sound insulation, acoustic planning and fire insulation,and can be used for different purposes. is one of the materials. Rockwool sheathing materials are good insulators and are somewhat more expensive insulation materials . Rockwool jacketing plates are a little heavy. For this reason, it is also possible to impose an additional load on the structure. m2 prices of stone wool sheathing boards are much more expensive than
