Creme crÃ¨me fraiche fraÃ®che is heavy cream that has been soured. And thickened it is similar to, sour cream but creme crÃ¨me fraiche fraÃ®che is thicker and not as. Sour as sour cream it is often used plain as a topping for fruit or other desserts and it can be added to sauces or other dishes to. make a creamy finish
In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy. The difference between the mass of 4 H atoms and 1 He atom is 0.02862 AMU which is only 0.71% of the original mass. This small fraction of the mass is converted into energy. If 4 grams (1/8 ounce) of H are converted to He, only 2.8x10-3 grams of the mass is converted to energy: How much energy is generated from converting such a tiny amount of mass? We can calculate by using Einstein's famous formula. E = mc 2
(It is also sometimes called fusion .). Another change that can occur for some solids is to change directly into a gas instead of changing into a liquid, and that is called sublimation. The reverse of this process can also occur. Some gases can be cooled down and changed directly into a solid.his kind of phase change--liquid to gas--is called evaporation or vaporization. Water vapor can in turn be cooled to form liquid water. This kind of phase change--from gas to liquid--is referred to as condensation.
