Explanation Formula used: Write the expression for conducted heat ( Q ) . Q = ( k A Δ T ) t L . (1) Here, k is thermal conductivity of material, A is cross-section area, Δ T is temperature difference between the ends, and L is length. Explanation: From Figures ( a ) and ( b ), the length of box in part a ( L a ) is double the length of box arrangement in part b ( L b ) . The area of box in part b ( A b ) is double than that of in part ( a ) ( A a ) . L a = 2 L b A b = 2 A a Modify equation (1), for box in part a . Q a = ( k A a Δ T ) t L a (2) Here, Q a is heat conducted in box arrangement of part a . Modify equation (1), for box in part b . Q b = ( k A b Δ T ) t L b (3) Here, Q b is heat conducted in box arrangement of part b

Energy transfer

The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.

Molar Specific Heat

Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)

Thermal Properties of Matter

Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which…
