The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energyRead More →
If you buy a property with a Share of Freehold, this means you own your property leasehold plus a share of the freehold for the building your property is in and the land it’s on. This usually applies to apartments. Can you fully own a Shared Ownership property? While theRead More →
Capillary rheometry. Creep (flow under a given force or stress) Stress relaxation (change in force for a given deformation) Thermal stability. How do you measure rheological properties? To measure the rheological properties of a material, rheometers are used. They measure the torque and the deflection angle of the measuring bob.Read More →
Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. … As shown in the figure above, electronegativity decreases from fluorine to iodine; the atoms become less effective at attracting bonding pairs of electrons as they grow larger. Which of the following propertyRead More →
In refining, the alkylation unit produces a high-quality gasoline blendstock by combining two LPG-range molecules to form one gasoline-range molecule. What is alkylation example? Alkylation is a chemical process by which an alkyl group is attached to an organic substrate molecule via addition or substitution. An alkyl group is anRead More →
When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl). What happens when atoms combineRead More →
Examples of colligative properties include vapor pressure lowering, freezing point depression, osmotic pressure, and boiling point elevation. What is Colligative property formula? The boiling point and freezing point change according to the number of particles that go into the solution. … i = the van’t Hoff factor kf = theRead More →
