Why can diamond not dissolve?
Why can diamond not dissolve? This is because of the relatively large amount of space that is “wasted” between the sheets. is insoluble in water and organic solvents – for the same reason that diamond is insoluble. Attractions between solvent molecules and carbon atoms will never be strong enough to overcome the strong covalent bonds […]
What are characteristics of groundwater?
What are characteristics of groundwater? Some of the most typical characteristics of groundwater are weak turbidity, a constant temperature and chemical composition and almost overall absence of oxygen. Circulating groundwater can have extreme variation in the composition with the appearance of pollutants and various contaminants. What is an example of groundwater? Groundwater originates from rain […]
Does increasing current increase magnetic field?
Does increasing current increase magnetic field? Yes, increasing current increases magnetic field strength. A moving charge produces a magnetic field around itself. Can a solenoid be reversed? A normal solenoid will not reverse direction if you reverse the polarity. They do not work by having north and south poles which attract or repel. That is […]
Can energy leave a system?
Can energy leave a system? First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed.
