The order should be:
3, 5, 1, 4, 2, 6
Answer:
potential difference
Explanation:
voltage = potential difference
dont confuse potential energy with electrical potential though.
Answer:
a) The temperature on the outer surface of the pipe is approximately 179.97 °C
b) The thickness of the insulation is approximately 0.857 m
Explanation:
We have;

αA = 200 W/(m²·K)
= (T₂ - T₁) × U
= (200 - 180) × 200 = 4,000
For the pipe, we have;

/U= (T₂ - T₁)
∴ 4000×
= (180 - T₂)
T₂ ≈ 179.97 °C
The temperature on the outer surface of the pipe, T₂ ≈ 179.97 °C
b) For the insulation, we have;

T₂ - T₃ = 179.97 °C - 40°C ≈ 139.97°C
/U= (T₂ - T₃)

The thickness of the insulation, x ≈ 0.857 m
Answer:
Degree of crystallinity affects polymer properties as increasing in crystallinity means higher the thermal stability and harder the material. Basically, crystallinity strongly affects polymer properties as it defines the degree of long range order in a material. Crystallinity is also determined by the size as well as molecular chain orientation.
