Calorimetry Heat is a form of energy that is transferred from one body to another due to temperature difference. calorie + metry Heat + Measurement It means measurement of heat . ***What is heat ? Heat is a type of energy and work is also a type of energy, so what is the difference between heat and work? Both heat and work are the modes of energy transfer in which one is the mechanical mode of energy transfer and the other is the nonmechanical mode of energy transfer. **HEAT :- Heat is a form of energy that is transferred from one body to another due to temperature difference. :- It is a scalar quantity. :- It may be - ve , +ve and zero . :- S I unit of heat is joule(J). :- C G S unit of heat is erg . :- 1 Joule = 10⁷ erg. :- Di...
There are three types modes of heat transfer. (1) Conduction (2) Convention (3) Radiation *** Conduction :-- Conduction is a method of heat transfer in which the molecules of a substance transfer heat by vibrating without changes its position . or Conduction is a mode of transfer of heat between two adjacent part of body because of their temperature difference. Length of the rod =L Temperature difference(Δ T)= (T₁ - T₂) **Heat current(H) :- Rate of flow of energy from hotter end to colder end is called heat current. [ H = d Q/dt] :- S I unit of heat current is j/s = watt(W). :- Dimensional formula of current is [ML²T⁻³] :...
