## Important Topics for HC Verma Concepts of Physics Part-2 Solutions Chapter 28: Heat Transfer

Kirchhoff’s Law

Kirchhoffs Voltage Law describes that “in any closed-loop network, the whole voltage around the loop is equivalent to the sum of all the voltage drops within the similar loop” which is also equivalent to zero. In other words, it is defined as the algebraic sum of all voltages within the loop must be identical to zero.

Nature of Thermal Radiation

Thermal radiation is the procedure by which energy, in the form of electromagnetic radiation, is produced by a heated surface in all directions and movements directly to its point of absorption at the speed of light. The thermal radiation does not need a prevailing medium to carry it.

Thermal Conduction

The transmission of energy inside a body by microscopic collisions of elements and movement of electrons within a body is known as thermal conduction. The colliding elements, which consist of molecules, atoms, and electrons, transmit disorganized microscopic kinetic and potential energy, jointly called internal energy.

Black-body radiation is the thermal electromagnetic radiation within or environment a body in thermodynamic equilibrium with its surroundings, produced by a black body.

Stefan Boltzmann Law

Stefan-Boltzmann law states that the overall radiant heat power produced from a surface is proportional to the fourth power of its absolute temperature. The law spread over only to black bodies, theoretical surfaces that captivate all incident heat radiation.

Newton’s Law of Cooling

The law that describes the amount of heat loss of a body is directly proportional to the variance in the temperatures between the body and its atmospheres is known as Newton’s law of cooling.
