As for the degree of heat and coldness of the object, please 3Q

The physical problem is related to the specific heat capacity of the object is that the heat absorbed or released by the object is different if the object rises or decreases by one degree Why does oil boil faster than water The melting point is a problem, but the specific heat capacity is also Water has to absorb twice as much heat as the oil to increase by one degree Similarly, in winter, the object you step on lowers the temperature is the same If the wooden floor is to release 5 joules to reduce the temperature by one degree, and the blanket is to release 10 joules to reduce the temperature by one degree, so its problem will be high, and it may also be the relationship between materials, and some materials have the function of heat preservation animal fur, etc.

The degree of heat and cold of an object is called temperature, and the commonly used units of expression are Celsius and Kelvin, where 1 Kelvin is equal to Celsius. Temperature is a manifestation of the translational kinetic energy between molecules in an object.

The faster the molecule moves, the higher the temperature, and the hotter the object; The slower the molecule moves, the lower the temperature and the colder the object. From the perspective of molecular motion theory, temperature is the symbol of the average kinetic energy of the molecular motion of the object, which is the collective manifestation of the thermal motion of the molecule, which is of statistical significance.

Celsius is the unit of measurement of the Celsius temperature scale (C), which is represented by symbols and is currently a widely used temperature scale in the world. It was first proposed by the Swedish astronomer Anders Resius in 1742 and has since been improved.

The meaning of Celsius refers to the temperature of a pure ice-water mixture of 1 degree at a standard atmospheric pressure of 0 degrees and the boiling point of water at 100 degrees, during which it is divided into 100 equal parts, each equal part is 1 degree, and is denoted as 1. Celsius is now included in the International System of Units (SI). t(k)=t( )t is the absolute temperature scale.

The degree of heat and cold of an object is called temperature, which is often expressed in the unit Celsius symbol

Temperature is a physical quantity that indicates how hot or cold an object isMicroscopically speaking, it is the intensity of the thermal motion of the molecules of an object. Temperature can only be measured indirectly by certain characteristics of an object as a function of temperature, and the scale used to measure the temperature value of an object is called a temperature scale.

It specifies the starting point (zero point) of the temperature reading and the basic unit for measuring the temperature. The SI unit is the thermodynamic temperature scale (k). Other temperature scales that are more commonly used internationally are Fahrenheit (°F), Celsius (°C) and the International Practical Temperature Scale.

The correct way to use the thermometer:

According to the temperature change range of the object to be measured, select a thermometer with an appropriate range;

Recognize the minimum scale value of the thermometer before use so that it can be read correctly;

When using, the glass bubble of the thermometer should be fully in contact with the measured object, do not touch the side wall or bottom of the container, and the reading can only be done after the thermometer is stable;

When reading, the thermometer must not leave the object to be measured, and the line of sight must be level with the upper surface of the liquid column of the thermometer.

(1) Temperature is a physical quantity that indicates the degree of cold and heat of an object, and the commonly used unit of temperature in its life is Celsius, and in the International System of Units, the unit of temperature is Kelvin;

Guoman! The degree to which an object is hot or cold is called temperature.

Can it be said simply? It's too long to write.!!

The degree of heat and cold of an object is called temperature, and temperature is a physical quantity that indicates how hot or cold an object is.

The degree of heat and cold of an object is called the physical quantity unit is Celsius, and we can accurately know the degree of heat and cold of an object through a thermometer

What is the process by which water becomes water vapor called?

The degree of heat and cold of an object is called temperature.

Temperature is a manifestation of the translational kinetic energy between molecules within an object. The faster the molecule moves, i.e., the higher the temperature; The slower the molecular motion, i.e., the lower the temperature, the colder the object.

Temperature is a physical quantity that indicates how hot or cold an object is, and microscopically it is the intensity of the thermal motion of the molecules of an object. Temperature can only be measured indirectly by certain characteristics of an object as a function of temperature, and the scale used to measure the temperature value of an object is called a temperature scale.

The starting point for temperature readings and the basic unit for measuring temperature are specified. SI units are thermodynamic temperature scales. Other temperature scales that are more widely used in the world are Fahrenheit (°F), Celsius (°C) and the International Practical Temperature Scale.

From the perspective of molecular motion theory, temperature is the symbol of the average kinetic energy of the molecular motion of an object, and temperature is the collective manifestation of the thermal motion of the molecule.

The main instrument used by meteorological stations to measure the temperature of the air near the ground is a glass tube thermometer containing mercury or alcohol. The thermometer itself has a greater ability to absorb the sun's heat than air, and the readings indicated after the sun are often higher than the actual temperature of the air around it, so when measuring the temperature of the air near the ground, the thermometer is usually placed in a louvered box ventilated on all sides about the ground.

The degree of heat and cold of an object is called temperature.

Objects are hot and cold to different degrees, and to denote this difference, people define the degree of hot and cold as temperature. It is inaccurate for people to judge the temperature of an object based on their senses, and for accuracy, people make thermometers.

In terms of working substances, thermometers are divided into: gas thermometers, liquid thermometers and solid thermometers. The gas thermometer is made according to the nature of the thermal expansion and contraction of the gas, the liquid thermometer is made according to the nature of the thermal expansion and contraction of the liquid, and the solid thermometer is made according to the nature of the thermal expansion and contraction of the solid.

How to express the temperature

Currently, there are three ways to express temperature, as described below.

1. Fahrenheit is a unit used to measure temperature.

2. The temperature measurement unit of the Celsius temperature scale (C), represented by symbols, is a temperature scale widely used in the world at present. Celsius is now included in the International System of Units (SI). t(k)=t( )t is the absolute temperature scale.

3. Kelvin (Kelvins) is a thermodynamic temperature scale or absolute temperature scale, which is a temperature unit in the International System of Units. Kelvin temperature is often represented by the symbol k, and its unit is open.
