Question

What is temperature? How can you differentiate it from heat ?

Answer 1

DEFINITION

temperature is the degree of hotness and coldness of a body. it is the average internal kinetic produced due to random collision of mollecules of the stubstance.

===============================

DIFFERENCE

heat -
1)heat is the energy which causes the sensation of hotness and coldness in a body.
2)the SI unit of heat is joule.
3)Heat is measured by the calorimeter.

temperature-
1)it id the degree of hotness and coldness in a body.
2)SI unit - Kelvin
3)it is measured by a thermometer.

Answer 2

A temperature is an objective comparative measurement of hot or cold. It is measured by a thermometer. Several scales and units exist for measuring temperature, the most common being Celsius (denoted °C; formerly called centigrade), Fahrenheit (denoted °F), and, especially in science, Kelvin (denoted K).

The coldest theoretical temperature is absolute zero, at which the thermal motion of atoms and molecules reaches its minimum – classically, this would be a state of motionlessness, but quantum uncertainty dictates that the particles still possess a finite zero-point energy. Absolute zero is denoted as 0 K on the Kelvin scale, −273.15 °C on the Celsius scale, and −459.67 °F on the Fahrenheit scale.

NATIONALAERONAUTICSANDSPACE ADMINISTRATIONThe Difference BetweenHeat and Temperature?We often refer to infrared radiation as being primarily heat (or thermal) radiation. But what exactly is heat, and how does it differ from temperature? Simply put, heat is a measurement of energy. All molecules contain some amount of kinetic energy, that is to say, they have some intrinsic motion. The hotter an object is, the faster the motion of the molecules inside it. Thus, the heat of an object is the total energy of all the molecular motion inside that object.Temperature, on the other hand, is a measure of the average heat or thermal energy of the molecules in a substance. When we say an object has a temperature of 100 degrees C, for example, we do not mean that every single molecule has that exact thermal energy. In any substance, molecules are moving with a range of energies, and interacting with each other as well, which changes their energies. But if we average the thermal energies of all the mol-ecules together, we can obtain an object's temperature.
