Question

Carbon dioxide produced by yeast in bread dough causes the dough to rise before baking during the baking process The carbon dioxide expands predict the final volume of 0.1 L carbon dioxide gas trapped in the bread dough as it’s heat it from 25°C to 98°C

Answer 1

$\begin{aligned} V_1 &= 0.1L\\ T_1 &= 25°C = (273 + 25)\ 298K\\ T_2 &= 98°C = (273 + 98)\ 371K\\ V_2 &=\ ? \end{aligned}$

According to Charles's law,

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

$\dfrac{0.1}{298} = \dfrac{V_2}{395}$

$V_2 = \dfrac{395×0.1}{298}$

$V_2 = 0.133L$

$\therefore$ The final volume of the carbon dioxide gas is 0.133L.
