The boiling point of titanium dioxide (TiO2) is quite high, due to its ionic and covalent bonding characteristics, making it stable at elevated temperatures. It typically boils around 2972°C (5382°F). Titanium dioxide is a compound with considerable industrial relevance, widely used in making paints, sunscreen, and food coloring (as E171), thanks to its excellent light-scattering properties and chemical stability. Its high boiling point underscores its thermal stability, making it suitable for applications subjected to high temperatures without degrading. However, for practical industrial applications, handling TiO2 under such extreme heat is rare, emphasizing more on its functionality at lower temperatures.

The maximum allowable stress for polypropylene typically ranges between 20 to 30 MPa for short-term loading. This value can significantly decrease under continuous or long-term stress due to the material's viscoelastic nature, which may lead to creep. Factors such as temperature, the presence of any additives, and the specific type of polypropylene (e.g., homopolymer, copolymer) can also influence this value. For engineering applications, it's crucial to consider these factors and consult material data sheets or perform specific testing under anticipated conditions to select a safe working stress level. Designs should incorporate a suitable safety factor to account for variability in material properties, environmental conditions, and the consequences of failure.

Foods rich in fiber include a wide range of fruits, vegetables, whole grains, legumes, nuts, and seeds. Berries, such as raspberries and blueberries, are excellent sources of fiber. Vegetables like broccoli, carrots, and Brussels sprouts, along with legumes including lentils, black beans, and chickpeas, offer significant amounts of fiber. Whole grains like oats, quinoa, and whole wheat products are also fiber-rich choices. Additionally, nuts and seeds, including almonds, chia seeds, and flaxseeds, incorporate essential fiber into the diet. Fiber is crucial for maintaining digestive health, regulating blood sugar levels, and assisting in cholesterol management. Incorporating a variety of these fiber-rich foods into meals and snacks can contribute to a balanced diet and promote overall health.
