# What is the difference between heat and temperature?

Relevance
• temperature is expressed in kelvins or degrees celsius, fahrenheit or whatever. Heat is expressed in Joules or calories

If you get a drop of 100 degree celsius water on your skin it will do more damage than an equally big drop of 180 degree oil. the oil has a higher temperature, but the drop of water contains more heat.

We're very fortunate that it takes a lot of heat to warm up water, as the water buffering the heat keeps temperatures on earth tolerable.

• Heat vs temperature ....

Heat is defined as the quantity of thermal energy transferred from a hot object to a cold object (thus, spontaneously) until thermal equilibrium is attained.

"Heat" is not the energy which something has (in totality), but rather, heat is energy which is transferred.  When you think of "heat" you should think of "transferred energy", NOT the "total energy."

Temperature is mistakenly called "kinetic energy."  That isn't true.  Temperature is simply an arbitrary number which is proportional to the average kinetic energy of particles.  The units in which temperature is given are NOT energy units.

Kinetic energy is "energy of motion" and is given by

KE = ½mv²

mass and velocity are neither the kinetic energy. The kinetic energy is proportional to mass and to velocity.

Kinetic energy can be given by

KE = ³/₂ kT ...... where k is Boltzmann's constant, 1.38x10^-23 J/K

T is not kinetic energy, T is proportional to kinetic energy.  For different temperature scales, there will be different values of Boltzmann's constant.

Therefore, it is important to understand that kinetic energy can be proportional to other measurements, and that kinetic energy is proportional to temperature.

• Temperature is a measure of the kinetic energy of molecules and atoms..Heat van infrared and microwave radiation and can be conducted and convected. Heat is energy. Temperature is a measure of kinetic energy.

No.  that's not quite true.  Temperature is NOT a measure of energy, kinetic or otherwise. Temperature is an arbitrary number which is proportional to the average kinetic energy. Temperature units are not energy units.

• Temperature is a neutral word that simply refers to the measurement of heat or cold, whereas "heat" describes an upward range or movement of measured temperature.

No. A nonsense definition of "heat"

• Way different, but kissing cousins!

Temperature does not depend on the size or type of object. For example, the temperature of a small cup of water might be the same as the temperature of a large tub of water, but the tub of water has more heat because it has more water and thus more total thermal energy.

No.  Not really.  Not the correct explanation for "heat."

• Temperature is the measurement of heat from its coldest to its hottest.

Nope.  Not even close.

• Heat is a type of energy.  Temperature is a measure of heat energy.

Heat is to temperature as foot is to shoe size.

Heat: It's hot outside.

Temperature:  It's 90 degrees outside.

Temperature is what measures heat. Temperature is a construct we use to objectively quantify the how much heat energy there is so that we can then analyze and compare one heat in relation to another heat.

Nope.  Poor analogy.  "Heat" is not simplistic description of how hot or cold something is.  This is essentially nonsense.
