Explain the transfer of heat by conduction, convection and radiation with examples. b) State their applications in daily life c)How much heat per day is lost by conduction through a concerete wall,...

Heat transfer is the movement of thermal energy from one object or substance to another. The three types of heat transfer are conduction, convection, and radiation. Each type of heat transfer has its own specific characteristics and applications in our daily lives.

Conduction: Conduction is the transfer of heat from one substance to another through direct contact, such as when a hot pan is placed on a cold surface. The heat is transferred from the hotter object to the cooler one until they...

1: A measure of the degree of disorder of a system is known asenthalpy.

2:If ΔThe efficiency of Carnot engine operating with reservior temperature at 100 K and –23 K will be(100+23)/100.

3:Coefficient of performance of an ideal refrigerator working between temperature T1 and T2 (T1 > T2) isBeta = T2 / (T1 - T2).

4:Entropy of a thermodynamic system does not change when this system is used for conduction of heat from a hot reservoir to a cold reservoir.

5:The second law of thermodynamics states...
