HEAT & TEMPERATURE

In most of the work we do, consider the heat and cold. In order for us to work comfortably and to play, the temperature needs to be adequate. It prevents food temperature from falling and prevents food temperature from falling. Gasoline engines operate by inflating and cooling hot gas; storms are caused by the collision of hot and cold air. Temperature control and thermal control are important in many aspects of human activity

Adding energy can heat something, but the added energy is brought about by light, electricity, friction, chemical reactions, nuclear reactions and other energies. When added for the first time to a substance, the energy may concentrate on one atom, but that atom immediately collides with another atom and diffuses energy. Ultimately, all atoms or molecules in a substance move faster. When added energy spreads throughout the material it is called thermal energy, thermal energy or simple heat. These three words all mean the same thing. Since heat is energy, there are energy units. In the SI system, this is Jules. Many other devices that measure thermal energy are commonly used. Calories and BTU are general thermal units

It can not directly measure heat, but it can detect its effect on substances. Temperature changes can usually be detected as temperature changes. Normally, when energizing many atoms, they move faster and become hotter. Similarly, if energy is removed from many atoms, they usually move less and become cooler

People often confuse heat and temperature because increasing thermal energy usually causes an increase in temperature. In a general lecture, the two terms have the same meaning: "I will heat it" means that you heat up, "I warm it" means you will raise the temperature That means that. Usually no one wants to distinguish between them.

However, increasing the heat does not necessarily raise the temperature. For example, when water boils, heating does not raise its temperature. This occurs at the boiling point of each material that may evaporate. At the boiling point, heat is applied to convert the liquid to a gas without increasing the temperature.

Heating a boiling liquid is an important exception, but as a general rule, increasing the heat increases the temperature. When energy is added to the liquid at the boiling point, it converts the liquid to the same temperature gas. In this case, the energy applied to the liquid enters, cutting the bond between the liquid molecules without causing a temperature change. The same happens when the solid becomes liquid. For example, ice and water can exist together at melting temperature. When applying heat to ice water, you can turn ice into water without changing the temperature. Generally, whenever there is a change in state, such as solid-liquid or liquid-gas transition, thermal energy can be applied without temperature change. Energy is necessary to change the state, so temperature will not rise even if energy is increased.

Thermal and temperature temperature and thermophysics focus on energy research. Energy has various forms - heat, light, sound, electricity, kinetic energy, potential. All of these forms of energy have the ability to function. Some form of energy can be converted to another form. For example, potential (stored chemicals) energy is converted to heat during the combustion process. Kinetic energy (due to friction) and electric energy can also be converted to heat. It is impossible to directly measure calories and calories are indicators of total kinetic energy of atoms or molecules in the body. Since heat is an energy form, the measurement unit is Joules (J) or kilojoules (kJ). The amount of heat of the body depends on body temperature, quality, material. Heat energy is always transferred from high temperature objects to cold objects. It does not depend on the quality or material of interest

Heat and temperature • Heat is a kind of energy. • Calories are indicators of the total kinetic energy of particles in the body - heat is measured in joules (J) or kilojoules (kJ). • The thermal energy flows from the high temperature body to the low temperature body. • The amount of heat in a human body depends on its quality, temperature, and the materials made from it. • High temperature. • Temperature is a measure of the average kinetic energy of particles in the body. • At absolute zero, the kinetic energy of the particle is zero. • As heat is applied to the body, the temperature rises (unless the condition changes). • The temperature scale used is Celsius (° C) and Kelvin (K).
