Difference between heat and temperature
What is temperature
The degree of hotness or coldness measured on a definite scale. Heat (Hotness and coldness are the results of the molecular activity ). As the molecules of a substance move faster, the temperature of that substance increases.
Explanation of temperature
In the measure of how hot (or cold) a body is. It is also a measure of the kinetic energy of the molecules. Atoms or ions of which matter is composed.
The [tooltip text=”SI unit” gravity=”nw“]International System of Units a system of physical units ( SI units ) based on the meter, kilogram, second, ampere, kelvin, candela, and mole, together with a set of prefixes to indicate multiplication or division by a power of ten.[/tooltip] of “temperature is Kelvin (K).
1K=1/273.16 Of temperature of the triple point of water is that temperature at which water Vapours and ice( liquid gas & solid ) are in equilibrium.
This actually occurs at 273.16k ( 0.01 degree C ).
Water triple bond:-
Water —————- Liquid
Ice —————- Solid
Gas —————- Vapours

What is Heat?
Is a form of energy and is measured in calories or [tooltip text=” BTU’s” gravity=”new”]British Thermal Units[/tooltip].
The SI Unit of heat energy is derived unit of work or energy i:e Which Joule/second

Heat is the energy possessed by a substance in the form of kinetic energy of atomic or molecular translation, rotation or vibration.
Heat in a body is the product of its mass, temperature and its specific heat capacity.
Observation effects of heat change in color temperature, Change of state and also volumetric change.
It is transmitted by conduction, convection, and radiation.
Heat is transmitted by conduction, convection, and radiation.
This may also be defined as that form of energy transferred between two bodies as a result of the difference in their temperatures. Heat will always be transferred from the hotter body to the colder body until the two ( or more ) are equal temperature.
The SI unit of “heat energy” is derived unit of work or energy. i.e: joule. This is the energy equivalent to the work performed as the point of application of 1 Newton moves through a distance of 1 meter.
Other Units in use are the calories (egs) 4.186J And British Thermal Unit (BTU’s)(TPS) 1055J.
