# The linear expansivity of brass is 2 x 10-5C-1. If the volume of a piece of bras...

### Question

The linear expansivity of brass is 2 x 10-5C-1. If the volume of a piece of brass is 15.00cm3 at 00C, What is the volume at 100oC?

A) 16.03cm3

B) 16.00cm3

C) 15.09cm3

D) 15cm3

### Explanation:

linear expansivity = $$\frac {V_2 - V_1}{V_1 {\times} {\Delta}{\theta}}$$

3 x 2 x 10-5 =$$\frac {V_2 - 15}{15 {\times} (100 - 0)}$$

V2 = 15.09cm3

## Discussion (2)

• linear expansivity = $$\frac {V_2 - V_1}{V_1 {\times} {\Delta}{\theta}}$$

3 x 2 x 10-5 =$$\frac {V_2 - 15}{15 {\times} (100 - 0)}$$

V2 = 15.09cm3

1. Y times the linear expansivity by three
