Question

When the risen (leavened) dough is placed in the oven to bake, pockets of gas and vapours in the dough expand. Why do the gas and vapours expand when heated? A Their molecules get bigger. B Their molecules move faster. C Their molecules increase in number. D Their molecules collide less frequently

Answer 1

Explanation:

Temperature can affect the rising of bread dough both directly and indirectly. ... Dry ingredients will absorb wet ingredients more slowly in cold temperatures (the molecules have less energy and so move more slowly themselves), and compounds of ingredients will behave in slightly different ways depending on the variation.

Answer 2

Answer:

B ) Their molecules move faster.
