What is crystallization process? Crystallization is a process whereby solid crystals are formed from another phase, typically a liquid solution or melt. Crystal. Crystal is a solid particle in which the constituent molecules, atoms, or ions are arranged in some fixed and rigid, repeating three-dimensional pattern or lattice. Why is acetone used for cleaning viscometer? […]
What are the negative effects of technology in the workplace?
What are the negative effects of technology in the workplace? Distraction is one of the most harmful impacts of technology at the workplace. The result? Cognitive scientist Gloria Mark says, is, people compensating for interruptions by working faster, leading to stress, frustration and pressure. All of this leads to poor productivity. Why the technology is […]
What is calcium phosphate formula?
What is calcium phosphate formula? Ca3(PO4)2 What is phosphate formula? PO₄³⁻ Is phosphate harmful to humans? Although phosphate is not harmful to humans, anthropogenic, or man-made, inputs of phosphorus are well known to have a significant impact on ecosystems, and can damage the health of rivers and lakes (known as eutrophication). What is the chemical […]
Is the water displacement method accurate?
Is the water displacement method accurate? The change in water level equals the volume of the submerged object. This method is more accurate than measuring water that has spilled out an overflowing beaker. You may need to remind students of the need for accuracy, not only in the weighing of the objects, but also in […]
At what pH enzymes are highly efficient?
At what pH enzymes are highly efficient? The enzyme activity is maximum at optimum pH which is between 5-7. Why do enzymes denature at high and low pH? Within the enzyme molecule, positively and negatively charged amino acids will attract. This contributes to the folding of the enzyme molecule, its shape, and the shape of […]
Why does a saucepan have a copper bottom but a plastic handle?
What happens to wavelength of energy increases?
What happens to wavelength of energy increases? The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength […]
What is the use of resonant frequency?
What is the use of resonant frequency? Chapter 6 – Resonance One use for resonance is to establish a condition of stable frequency in circuits designed to produce AC signals. Usually, a parallel (tank) circuit is used for this purpose, with the capacitor and inductor directly connected together, exchanging energy between each other. What are […]
Is it safe to heat magnets?
Is it safe to heat magnets? When heated above 176° Fahrenheit (80° Celsius), magnets will quickly lose their magnetic properties. The magnet will become permanently demagnetized if exposed to these temperatures for a certain length of time or heated at a significantly higher temperature (Curie temperature). Why Does heat destroy magnets? Excessive heat causes atoms […]
