Explanation Given that the specific heat of the one material is twice of another material. The amount of heat required to raise the temperature of unit mass of substance by one degree is called the specific heat of the substance. And the SI unit for specific heat is J/K ⋅ kg (joule per Kelvin and kilogram). Write the expression for heat. Δ Q = m c Δ T (I) Here, Δ Q is the amount of heat absorbed by a substance, m is the mass, Δ T is the change in temperature and c is the specific heat. Solve Equation (I) for c . c = Δ Q m Δ T (II) The specific heat of the one material is twice of another material is expressed as, c 1 = 2 c 2 (III) From Equation (II) the specific heat for the one of the materials is expressed as, c 1 = Δ Q

First law of Thermodynamics

The word thermodynamics consists of two words: thermo- and dynamics. Dynamics means the study of motion. The field of thermodynamics is all about the study of the movement of heat. In a more meaningful way, it is stated as the study of the transfer of en…
