Tunatumia fomula $T_K = T_C + 273$.

Halijoto ya awali, $T_1 = 27^\circ C = 27 + 273 = 300\,K$.
Halijoto mpya, $T_2 = 77^\circ C = 77 + 273 = 350\,K$.

Sheria ya Charles inasema kwamba kwa kiasi fulani cha gesi kwenye shinikizo lisilobadilika, ujazo wa gesi unalingana moja kwa moja na halijoto yake kamili. Fomula yake ni:

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

Ambapo $V_1$ ni ujazo wa awali, $T_1$ ni halijoto ya awali, $V_2$ ni ujazo mpya, na $T_2$ ni halijoto mpya.

Tunapewa $V_1 = 120\,cm^3$, $T_1 = 300\,K$, na $T_2 = 350\,K$.

$$V_2 = \frac{120\,cm^3 \times 350\,K}{300\,K}$$ $$V_2 = \frac{42000\,cm^3}{300}$$ $$V_2 = 140\,cm^3$$

Ujazo mpya wa gesi ni $\boxed{\text{140\,cm}^3}$.
