Heat:
Heat is a transfer of energy other than by work or transfer of matter. Heat flows spontaneously from a hotter body to a colder one whenever a suitable physical pathway exists between bodies, and always results net in a net increase in entropy.
Temperature:
A temperature is a comparative objective measure of heat and cold. It is measured, by a thermometric material, detection of heat radiation, or by particle velocity or kinetic energy. It may be calibrated in any various temperatures scales, Celsius, Fahrenheit, Kelvin, etc. measurements with a small thermometer.

| Related | Heat is a measure of how many atoms are there in a substance multiplied by how much energy each atom passes. | Temperature is related how fast the atoms within a substance are moving. The temperature of an object is like the water level – it determines the direction in which “heat” will flow. |
| Particles | Heat is a measure of how many atoms there are in a substance multiplied by how much energy each atom possesses. | Temperature is related to how fast the atoms within a substance are moving. The temperature of an object is like the water level- it determines the direction in which ‘heat’ will flow. |
| Ability to do work | Heat has the ability to do the work. | Temperature can only be used to measure the degree of heat. |
