Question

what is mutual relation between heat and temperature.....

Answer 1

Heat and temperature are two different but closely related concepts. Note that they have different units: temperature typically has units of degrees Celsius (^\circ\text C∘Cdegree, C) or Kelvin (\text KKK), and heat has units of energy, Joules (\text JJJ). Temperature is a measure of the average kinetic energy of the atoms or molecules in the system. The water molecules in a cup of hot coffee have a higher average kinetic energy than the water molecules in a cup of iced tea, which also means they are moving at a higher velocity. Temperature is also an intensive property, which means that the temperature doesn't change no matter how much of a substance you have (as long as it is all at the same temperature!). This is why chemists can use the melting point to help identify a pure substance-−minusthe temperature at which it melts is a property of the substance with no dependence on the mass of a sample.

Answer 2

At the atomic scale, the kinetic energy of atoms and molecules is sometimes referred to as heat energy. Kinetic energy is also related to the concept of temperature. Temperature is defined as the measure of the average speed of atoms and molecules. The higher the temperature, the faster these particles of matter move.
