Heat may be defined as energy in transit from a high temperature object to a lower temperature object. Heat is form of energy which produces the change in temperature in any substance. The heat is denoted by Q. The Heat formula is given by Where, m is the mass of the body, C is the specific heat, Δ T is the temperature difference. Heat formula is used to find the heat transfer, mass, specific heat or temperature difference if some of the quantities among these are given. Heat is expressed in Joules (J). read less

The Best Tutor You Can Have, Students Come First, UPSC Aspirant

The Joule's law states that the quantity of heat produced in a resistor is directly proportional to: (i)the square of current for a given resistance, (ii) the resistance for a given current, and (iii) the time for which the current flows through the resistor, i.e., H = I2Rt.

The formula for Heat H = MST, where M is the mass in kg, S is the specific heat and T is the temperature in degree C. S depends on the property of the substance and is defined as the amount of heat required to raise the temperature of unit mass of the substance by 1 degree Censius
