What is a benefit of using a wood I-joist for floor joists instead of dimensional lumber? I-joists are typically available in long lengths and because they're lightweight, have the advantage of being easily handled at the jobsite without the need for costly handling equipment. Their "I" configuration provides high bending strength and stiffness characteristics. Are floor trusses stronger than joists? Span longer distances than traditional joists, removing the need for walls in some areas. Lighter weight. Stronger than traditional joists. Wider nailing surface (making the building process easier) What are two benefits of selecting I-joist over dimensional lumber in floor...

Does freezing kill bread yeast? Yes it is possible to freeze pizza and bread dough that contains yeast and has already risen once. Yeast is killed off at higher temperatures but remains relatively unaffected if frozen (you can also freeze blocks of fresh yeast to use at a later date). Is yeast still good if frozen? Newly purchased yeast (with good purchase-by date), can be stored in a cool location (pantry or cabinet), refrigerated, or frozen for up to two years. Once the yeast is opened, it's best kept in the refrigerator to use within four months, and six months...

What are the chemical reactions in baking? Chemical Reactions That Occur During BakingProtein Bonding. Flour contains two important proteins -- glutenin and gliadin. Magic Leaveners. Leavening agents -- such as yeast, baking powder and baking soda -- give baked dough its pillowy lightness. Maillard Reactions. Flavors of Caramelization. Why is baking bread an example of a chemical change? Why is baking bread and example of a chemical change? Heating up the bread causes the dough to rise because of the heat. This is a chemical change because it is a transition from Mercury Oxide to Mercury and Oxygen. What are...
