### Question

A fixed mass of gas of volume 600cm3 at a temperature of 27oC is cooled at constant pressure to a temperature of 0oC. What is the change in volume?

A) 54cm2

B) 273cm2

C) 300cm2

D) 546cm2

E) 600cm2

### Explanation:

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

T2 = 0 + 273 = 273k

V1 = 600

T1 = 27 + 273 = 300k

V2 = $$\frac{V_1T_2}{T_1}$$ = 546cm

V1 - V2 = 54cm

## Dicussion (1)

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

T2 = 0 + 273 = 273k

V1 = 600

T1 = 27 + 273 = 300k

V2 = $$\frac{V_1T_2}{T_1}$$ = 546cm

V1 - V2 = 54cm
