Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

2. Electrical components often failure due to thermal overload. It follows that thermal analysis of electrical components is critical to their longevity. Consider a silicon chip which is sitting atop a ceramic substrate with 35 mm2 of exposed surface area. Operating at steady state, the chip can pull up to 120 mW of power. The chip surface is cooled by convection from flowing air at 20°C. The heat transfer from the chip to the air is given by Q = hA(T, – T) where h is the thermal convection coefficient, A is the exposed surface area, and Tb and Tr are absolute temperatures of the body and coolant fluid, respectively. h of the flowing air is found to be 250 W/(m2-K).
