1. S.H.M is represented by simple sine or cosine function. 2.Restroing force always opposed the increase in displacement. 3.Particle moved back and forth about its mean position with constant amplitude and frequency. 4.The motion of the particle is periodic. 5.Particles oscillates with large vibrations unless it will said to be vibratory motion.

Suppose the refrigerator as a device that transfer heat from the box to the surrounding. As a result of it the room around the refrigerator is warmed as it receives heat removed outside from the box(refrigerator). If we leave the door open,heat is recycled from the room to the refrigerator and back to the room. So the temperature of the room increases as the energy is moving around the circle(from refrigerator to surrounding and again to the refrigerator).
