### Question

If the volume of a given mass of a gas at 0ºc is29.5cm$$^3$$. What will be the volume of the gas at 15ºc, given that the pressure remains constant.

A)
31.6
B)
62.2
C)
32.7
D)
31.1

### Explanation:

Charles' law is a special case of the ideal gas law in which the pressure of a gas is constant.

Charles's law defines the direct relationship between temperature and volume.

GIVEN DATA: V$$_1$$ = 29.5cm$$^3$$,  V$$_2$$ = ? ,  T$$_1$$ = 0ºc or 273k,  T$$_2$$ = 15ºc or 288k

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

V$$_2$$ = $$\frac{V_1 x T_2}{T_1}$$ → $$\frac{29.5 x 288}{273}$$

V$$_2$$ = 31.1cm$$^3$$
