with butter and sugar. Or putting it in the oven.
A puffy lid on a container of pre-made cookie dough can indicate that bacteria may have produced gas, which could mean the dough is spoiled. It's best to err on the side of caution; if the dough smells off or has an unusual appearance, it's safest to discard it. Always check for any signs of spoilage before using.
Cookie dough recipes generally call for either baking soda or baking powder, which create gas that expands and causes the dough to rise while baking.
Baking soda helps cookies to rise and spread during baking by producing carbon dioxide gas when it reacts with acidic ingredients in the dough. This reaction creates air pockets in the cookie dough, resulting in a lighter texture and softer cookie.
carbon dioxide is he gas excreted by yeast metabolising sugars in the dough making it rise.
A cookie is solid and it its edible as food.
There are tiny bubbles of air trapped in the dough. As the dough rises the bubbles expand into the holes you refer to. it is a gas.the best example for gas in solid is bread. (u can type this questions in yahoo answers so u can get more information)
A solid.
The gas that bubbles in the dough to make it rise is carbon dioxide. This gas is produced during fermentation by yeast or chemical leavening agents. The carbon dioxide forms bubbles in the dough, causing it to expand and rise.
A solid.
Baking soda is a rising agent. Some others are baking powder, yeast, beaten egg whites and other things. With out it your cookies will be thin, flat, hard and heavy, instead of light and/or crunchy. Baking powder is relatively slow acting, especially when compared to baking soda (sodium bicarbonate). Baking powder is a mixture of baking soda, a base, and cream of tartar, an acid, when mixed with a liquid the two combine and a gas, carbon dioxide,CO2, is released. The tiny bubbles make the dough rise. The liquid is usually added last thing before baking so the bubbles don't just dissipate into the air. The cookies go into a hot oven so the dough begins to set up and the bubbles separate the small particles of firm dough instead of just being baked as bubbles into the otherwise hard cookie.

Yeast is added to bread along with moisture and sugar, and the dough is kept in a moist, warm environment. During this rising time, the yeast consumes the sugar in the dough and release CO2 gas, which is trapped in the dough and causes the dough to rise. When the dough is baked, the yeast is killed, but the bubbles created by the gas remain.
