Answer:
The percentage of silicon atoms per unit volume that are displaced in the single crystal lattice = 0.001 %
The percentage of silicon atoms per unit volume that are displaced in the single crystal lattice with boron atoms = 0.4 × %
Explanation:
No. of phosphorus atoms = 5 ×
The volume occupied by a single Si atom
2 ×
= 5 ×
Put the values in above equation we get
PCT = %
These are the percentage of silicon atoms per unit volume that are displaced in the single crystal lattice.
(b).
No. of boron atoms = 2 ×
The volume occupied by a single Si atom
2 ×
= 5 ×
Put the values in above equation we get
PCT = 0.4 × %
These are the percentage of silicon atoms per unit volume that are displaced in the single crystal lattice.
Answer:
Q = 378.247 Bt/hr
Explanation:
given data:
diameter of container = 3 m
so r = 1.5 m
T1 = 50°C
T2 = 100°C
depth y = 3 ft
Heat transfer is given as Q
Where
S = Shape factor for the object
S = 25.132 ft
Q = 25.132*0.301 *(100-50)
Q = 378.247 Bt/hr
