16 During evaporation, molecules escape rapidly from the surface of a liquid.What happens to the average energy of the molecules of the remaining liquid and what happens to the temperature of the remaining liquid? A average energy of temperature of remaining molecules remaining liquid Adecreases dec...
One problem with electron microscopes is that they cannot be used to study living specimens because the specimen must be held in a vacuum chamber; that is, all the air and liquid must be removed. For a biologist studying a living process, such as the whirling movement of a bacterium, a ...
Undergoing a biopsy procedure can be a traumatic experience, and waiting for results adds to the stress. Here is the step-by-step process all biopsies go through in the lab.
Slime activators (borax, saline solution, or liquid starch) change the position of the molecules in the glue in a process called cross-linking! A chemical reaction occurs between the glue and the borate ions, and slime forms the new substance. Instead of flowing freely as before, the molecule...
While you can't mix pee and bleach, there is a way to deal with the situation when your whole house smells like dog urine. There are a lot of commercially available options marketed as enzymatic cleaners. These products contain enzymes, which are biological molecules that break down compounds...
Is evaporation of water a physical change or chemical change? Once the ice cube melts, what happens to the liquid water that it produces? What chemical reaction produces water? When water begins to boil, hot water at the bottom rises and replaces the cold water at the top. Heat is tran...
If a minimal amount of shear force (maybe almost negligible) is applied on a matter, and this matter deforms continuously, then this matter is known as fluid. Usually, gases and liquids are called as fluid.Answer and Explanation: In the world, all the fluid changes its properties under ...
Chemical reactions involve the interaction of atoms' electron clouds... Learn more about this topic: Basic Properties of Chemical Reactions from Chapter 2/ Lesson 14 71K Chemical reactions, when molecules interact to create new substances, can be written as equations. Learn more about the basic...
Water is one of the primary life forces on the planet, enabling biological life to thrive. It exists in the clouds; in the sea, rivers, and oceans; and even underground! Water circulates between the land, bodies of water, and atmosphere through the water cycle in stages that include ...
The heroes of our story were conceived in this oil refinery. The plastic in their bodies was formed by chemically bonding oil and gas molecules together to make monomers. In turn, these monomers were bonded into long polymer chains to make plastic in the form of millions of pellets. Those ...
