### Question

A column of air 10.0cm long is trapped in a tube at 27oC. What is the length of the volume at 100oC?

A) 12.4cm

B) 13.7cm

C) 18.5cm

D) 37.0cm

### Explanation:

$$\frac{V_1}{T_1}$$ = $$\frac{V_2}{T_2}$$

$$\frac{10\times A}{27 + 273}$$ = $$\frac{L\times A}{100 + 273}$$

L = 12.43cm

## Dicussion (1)

• $$\frac{V_1}{T_1}$$ = $$\frac{V_2}{T_2}$$

$$\frac{10\times A}{27 + 273}$$ = $$\frac{L\times A}{100 + 273}$$

L = 12.43cm
