Question

CHECK Point 2
Fill in the blanks.
1.Coefficient of linear expansion of copper is_____
2 Coefficient of linear expansion =______x coefficient of volume expansion (Y).
3.solid have _____kind of thermal expansion​

Answer 1

Answer:

1. 1.75×10-5 C°-1

2. Y/3

3. 3

Explanation:

1. It is always same for a particular metal or substance and slightly changes w.r.t temperature.

2. beta (Y) = 3 alpha(co-efficient of linear expansion)

co-efficient of linear expansion= (Y) / 3

3. linear expansion,volumetric expansion and superficial expansion (aerial expansion)
