Answer:
Option C
Explanation:
We have to check range of all options first
For A:
Largest Value: 5
Smallest Value: 1
So range = Largest value - smallest value
5-1 = 4
For B:
Largest Value: 6
Smallest Value: 4
Range = 6-4 = 2
For C:
Largest Value: 9
Smallest Value: 1
Range = 9-1 = 8
For D:
Largest Value = 9
Smallest Value = 3
Range = 9-3=6
So, the data set in option C has the largest range
Answer:
The change in volume is 
Solution:
As per the question:
Coefficient of linear expansion of Copper, 
Initial Temperature, T =
= 273 K
Final Temperature, T' =
= 273 + 100 = 373 K
Now,
Initial Volume of the block, V = 



where
V' = Final volume
