Question #1
The temperature coefficient of resistance of a semiconductor is
A. Zero
B. Positive
C. Negative
D. Infinite

Correct Answer: Option C


Explanation:
Resistance decreases with temperature for semiconductors, so α negative.

Question #2
According to Newton's Law of Cooling, the rate of loss of heat from a body is strictly proportional to:
A. The fourth power of the temperature difference.
B. The absolute temperature of the surroundings.
C. The temperature difference between the body and its surroundings.
D. The square of the temperature of the body.

Correct Answer: Option C


Explanation:
Newton's Law of Cooling is a practical approximation stating that the rate of heat loss of a body is directly proportional to the difference in temperatures between the body and its immediate environment, provided this temperature difference is relatively small. The equation is dQ/dt = -k(T_body - T_surroundings).
