What are the two SI units for work? The SI unit of work is the joule (J), the same unit as for energy. What is the equation for work in thermodynamics? Calculation of Work In thermodynamics, the work involved when a gas changes from state A to state B is simply: WA→B=∫VBVAPdV W A → […]
What metal has a density of 19.3 g ml?
What metal has a density of 19.3 g ml? Gold Why is a liquid silver less dense than solid silver? The same mass divided by a larger volume results in a smaller value for density. Therefore, liquid silver is less dense than solid silver. What are the two factors that determine a material’s density? The […]
Can a quark be split?
Can a quark be split? Quarks,and leptons are thought to be elementary particles, that is they have no substructure. So you cannot split them. Quarks are fundamental particles and cannot be split. What happens if you cut a quark in half? And, if you cut them in half, you don’t wind up with a single […]

What would happen if helium lost an electron?
What would happen if helium lost an electron? What happens to a helium atom when it loses an electron? Notes: When a helium atom loses electrons, it get positive charge because the number of protons in the helium atom becomes greater than the number of electrons. When helium atom loses one electron it becomes positive […]

Why Sulphuric acid is called as King of chemicals?
Why Sulphuric acid is called as King of chemicals? Sulphuric acid (H2SO4) is called the “King of Chemicals” because it is used in the preparation of a very large number of other useful chemicals such as hydrochloric acid, nitric acid, dyes, drugs etc. Sulfuric acid has the properties of strong acidic nature and is corrosive. […]
What is the salt formula?
What increases solubility?
What increases solubility? For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions. How does crushing affect solubility? Crushing it has increased the surface […]
