Should carrots float or sink? What’s happening in there? The carrot is more dense than fresh water so the carrot sinks in fresh water. When salt is dissolved in the water, the density of the water increases until the salt water becomes more dense than the carrot which makes the carrot float in the salt […]
Can you charge a conductor?
Can you charge a conductor? Explanation: While you can charge a dielectric (non conductive, like plastic) object rubbing, you cannot charge a conductor (like a metal) rubbing. If you add a charge in one zone of the conducting object, the other charges will automatically re-arrange to neutralize the charge. Is salt water an insulator? For […]
Why is cu2+ more common than Cu+?
Why is cu2+ more common than Cu+? Stability depends on the hydration energy (enthalpy) of the ions when they bond to the water molecules. The Cu2+ ion has a greater charge density than Cu+ ion and thus forms much stronger bonds releasing more energy. Is Copper 1 or 2 more common? Copper is the earth’s […]
In which nebula do we live?
What weighs more vodka or water?
What weighs more vodka or water? Dense materials sink, and less-dense materials float. Water is denser than alcohol, so the alcohol floats on top of the water. In higher temperature, the density is lower. Does alcohol and water mix? Because water molecules are polar, any liquid that does not have polar molecules—such as oil—is usually […]
What are 2 forms of energy?
What are 2 forms of energy? Many forms of energy exist, but they all fall into two basic categories: Potential energy. Kinetic energy. What is energy made of? 6 Answers. Energy is not made of anything, energy is a term used to describe a trait of matter and non-matter fields. When matter has velocity, for […]
Is a compass reliable?
Is a compass reliable? Overall, Consumer Reports gave the 2018 Compass a reliability rating of 11%, the lowest of all SUVs in its segment. The 2019 and 2020 models of the Compass have a higher predicted reliability score of about 3 out of 5, but that may change as owners drive their Compasses around some […]
What do you mean by real and virtual image?
What do you mean by real and virtual image? A real image is the collection of focus points actually made by converging rays, while a virtual image is the collection of focus points made by extensions of diverging rays. In other words, it is an image which is located in the plane of convergence for […]
What type of natural selection has occurred?
What type of natural selection has occurred? Types of natural selection: Different types of natural selection can impact the distribution of phenotypes within a population.In (a) stabilizing selection, an average phenotype is favored.In (b) directional selection, a change in the environment shifts the spectrum of phenotypes observed.In (c) diversifying selection. Is natural selection true? Natural […]
What are the mobile electrons of a pure metal called?
What are the mobile electrons of a pure metal called? The Metallic Bond The electrons in the outer energy levels of a metal are mobile and capable of drifting from one metal atom to another. What metal can withstand 6000 degrees? Tantalum carbide (TaC) and hafnium carbide (HfC) are refractory ceramics, meaning they are extraordinarily […]
