Question

difference between heat and temperature

Answer 1

$\huge\textbf{Heat :}$


1) It is a form of energy that produces sensation of warmth.


2) It is the sum of all Kinetic energy, Potential energy of molecules.


3) It depends upon mass, number of molecules and size.


4) It's S.I. unit is Joule (J)

and practical unit is Calories.

1 Calorie = 4.2 J


5) It is measured by using calorimeter.

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


$\huge\textbf{Temperature :}$


1) It is degree of coldness or hotness of a body.


2) It is proportional to the kinetic energy of molecules of the body.


3) It depends upon speed of molecules.


4) It's S.I. unit is Kelvin (K).


5) It is measured by using thermometer.


→ Temperature is something which determines the direction of flow of heat (from high temperature to lower temperature).

Answer 2

• Heat and temperature are connected, but contrary to popular belief, they don't mean the same thing.
• Knowing the distinction between heat and temperature can lead to a clearer understanding of the world around us.
• In this composition, we will define both heat and temperature and reach an understanding of how they're related, but not identical.

• The reason why the conception of heat and temperature might be mixed up is because of how nearly they're related in real life.
• However, its temperature goes up, If you add heat to something.
• If you add heat to something.However, you're taking its heat down,
• If you add heat to something.However, you're taking its heat down, If you reduce temperature. Let’s look at what they actually represent.
• Heat is the total energy of the stir of the motes of a substance, whereas temperature refers to the measure of the average energy of the movements of the motes in the substance.
• The heat is dependent on factors like the speed of the patches, the size of the patches and the number of patches,etc.
• The temperature, on the other hand, is independent of these factors.
• For illustration, let’s compare a hogshead of water with a mug of water.
• The water in the hogshead and the mug can be at the same temperature but by the virtue of the number of patches in the hogshead, the water in the hogshead has further thermal energy in it and thereby further heat indeed though they've the same temperature.
• Temperature is a number that relates to the energy held by the motes of a substance, which directly relates to the kinetic energy held by the patches of the substance.
• The SI Unit of temperature is Kelvin. As we said before, the temperature is directly related to the kinetic energy of the motes, thus if you double the temperature( Kelvin) of a substance, you double the average kinetic energy held by those motes.
