We are generally thinking about heat and temperature both are same but actually heat is a energy and temperature is measurement of heat quantity.
And also we
thought that heat needs some medium to contact and transfer its energy like
sound. But the radiation does not compulsion for medium for transfer energy. Without
any medium heat can radiate one place to another place. For instance sun
radiation.
Another general
mindset of common people, boiling water can causes big effect of heat rather
than reality is steam causes much more effect of heat than boiling water.
The above concept is simplify in the
below tabular column.

Common Misconception |
Fact |
|
Heat and
temperature are same. |
Heat is a form of
energy. Temperature is a measure of degree of hotness or coldness of a body. |
|
Transfer of heat
from one body to another needs a medium. |
Radiation of heat
does not require any physical medium. (Example: Heat from sun reaches earth
through vacuum) |
|
Boiling water can
cause more damage. |
Steam causes more
damage due to latent heat as compared to boiling water. |
Heat is an energy temperature
is measurement of quantity of heat. Heat is an energy, work, and causes some
effect but temperature is just like mathematical measurement work.
|

Temperature |
|
Heat is a form of
energy |
Temperature
indicate the thermal condition of a body i.e., how much hot (or) how much
cold the body is: |
|
Heat is the cause |
Temperature is the
effect. |
|
Heat contents of a
body do not decide the direction of heat flow from the body. |
Temperature of a
body decides the direction of heat flow from the body. |
|
S.I. unit of heat
is joule (J) |
S.I unit of
temperature is Kelvin (K) |
These are the measuring scale for temperature which is widely
using all branches of science and technology.
The SI unit of temperature is Kelvin but we also use Fahrenheit and Celsius
for many other temperature measurement process.
