How does temperature increase yield? An increase in temperature favours the reaction that is endothermic (the reverse reaction) because it uses up energy. If the temperature is increased, then the yield of ammonia (NH3) decreases. A decrease in temperature favours the reaction that is exothermic (the forward reaction) because it produces energy. How does temperature […]

What is law of Malus Brewster law?
What is law of Malus Brewster law? Brewsters Law Formula When unpolarized light of a certain wavelength is incident upon the surface of a transparent substance it experiences maximum plane polarization at the angle of incidence whose tangent is the refractive index of the substance. How do you use Malus law? For the second polarizer, […]
Does increasing voltage increase power?
Does increasing voltage increase power? As we already know that in a step-up transformer, if voltage increases, the current decreases where power is same (as transformer only step-up or step-down the value of current and voltage and doesn’t change the value of power). Similarly, voltage decreases when current increases in a step-down transformer. How fast […]
How do you calculate serial dilution concentration?
How do you calculate serial dilution concentration? In serial dilutions, you multiply the dilution factors for each step. The dilution factor or the dilution is the initial volume divided by the final volume. For example, if you add a 1 mL sample to 9 mL of diluent to get 10 mL of solution, DF=ViVf = […]
What is the difference between hydraulic and hydrostatic?
What is the difference between hydraulic and hydrostatic? “A hydraulic drive system is a quasi-hydrostatic drive or transmission system that uses pressurized hydraulic fluid to power hydraulic machinery . The term hydrostatic refers to the transfer of energy from pressure differences, not from the kinetic energy of the flow. What are the requirements for a […]
How important is social perception?
How important is social perception? Social perception is one important component of social competence and social success (including peer acceptance and friendship). In addition to social perception, socially competent people must have knowledge of social rules, roles, routines, and scripts in their social lives. How does social perception influence behavior? Recent research by Bargh et […]
What are the effects of mutation?
What are the effects of mutation? Sometimes, gene variants (also known as mutations) prevent one or more proteins from working properly. By changing a gene’s instructions for making a protein, a variant can cause a protein to malfunction or to not be produced at all. What is an example of deletion mutation? The deletion creates […]
Does density increase with depth in Earth?
Does density increase with depth in Earth? According to Lambert, the mean density of earth is 5.51 to 5.52. The first attempt to determine the density in the earth as a function of the depth has been based on the assumption that the density increases continuously with depth. What are the factors affecting the temperature […]
What is the law of negativity?
What is the law of negativity? In other words, we receive positive or negative energy in accordance to what signal we emit. For example, one who complains criticizes and finds fault with others will attract negative events and people into their lives. The negative emotions one emits will bring back to that person energy of […]
