Q-heat

M-specific heat of object (look-up table)

T2-the final temperature of the object

T 1-initial temperature of the object

: heat:

Heat refers to the energy transferred due to temperature difference; It also refers to the energy generated by the temperature rise of 1 gram of water at 1 atmosphere 1 degree Celsius; Between objects with different temperatures, heat is always transferred from high-temperature objects to low-temperature objects; Even in the isothermal process, the temperatures between objects are constantly slightly different, and a new balance is constantly reached through heat transfer.

All life activities of human body need energy, such as synthetic reaction of substance metabolism, muscle contraction, gland secretion and so on. And these energies mainly come from food. Nutrients contained in animal and plant foods can be divided into five categories: carbohydrates, lipids, protein, minerals and vitamins, and water is six categories.

Among them, carbohydrates, fats and protein can release energy through in vivo oxidation. These three are collectively referred to as "productivity nutrients" or "heat sources". Due to the existence of temperature difference, the energy converted in the process of energy conversion; And this transformation process is called heat exchange or heat transfer; The metric system of heat is joule.

Temperature:

Temperature is a physical quantity that indicates the degree of heat and cold of an object, and it is the intensity of molecular thermal motion of the object at the microscopic level. According to an observable phenomenon (such as the expansion of mercury column), the degree of heat and cold is measured by one of several arbitrary scales. Temperature can only be measured indirectly through some characteristics of an object that changes with temperature. The scale used to measure the temperature value of an object is called a temperature scale. It specifies the reading starting point (zero point) of temperature and the basic unit for measuring temperature.

The international unit is the thermodynamic temperature scale (K). At present, other temperature scales widely used in the world are Fahrenheit scale (F), centigrade scale scale (C) and international practical temperature scale. From the point of view of molecular motion theory, temperature is a sign of the average kinetic energy of an object's molecular motion. Temperature is the collective expression of a large number of molecular thermal movements, which has statistical significance.
