What happens to molecules when the kinetic energy decreases? Explanation: Kinetic energy of the molecules of a subsance is directly proportional to the temperature of molecule So as the kinetic energy decrease, temperature also decreases. What is the average kinetic energy of any substance at 0 K? 0 Kelvin is the temperature where the is […]
What is the purpose of a reference?
What is the purpose of a reference? Referencing allows you to acknowledge the contribution of other writers and researchers in your work. Any university assignments that draw on the ideas, words or research of other writers must contain citations. Referencing is also a way to give credit to the writers from whom you have borrowed […]
Is it better to get fit before playing sports or play sports to get fit?
Is it better to get fit before playing sports or play sports to get fit? Being fit is very important to overall health. However, when looking at sports performance the goals tend to be more specific and the level of training higher. Just by being fit does not necessarily mean that one is ready for […]
Where is foreshortening used?
Where is foreshortening used? Foreshortening is a technique used in perspective to create the illusion of an object receding strongly into the distance or background. The illusion is created by the object appearing shorter than it is in reality, making it seem compressed. Are foreshortening and perspective the same thing? Perspective is the mathematical rule […]
Is fracking good or bad?
Is fracking good or bad? In the U.S. alone, around 13 million metric tons of methane is released annually from natural gas wells alone. Fracking well sites are the source of a number of other air pollutants, which are less common than methane, but arguably more harmful to local populations. Where is fracking banned? Four […]
What is loss formula?
Why diesel engines are called CI engines?
Why diesel engines are called CI engines? Diesel engines are sometimes called compression-ignition engines because initiation of combustion relies on air heated by compression rather than on an electric spark. In a diesel engine, fuel is introduced as the piston approaches the top dead centre of its stroke. What is the difference between SI & […]
What are the disadvantages of using aluminum wire?
What are the disadvantages of using aluminum wire? The disadvantage of aluminum wiring is that it must be installed correctly to avoid the risk of house fires. When a current runs through aluminum wiring it causes the metal to expand. This creates a cycle of expanding and contracting called “cold creep.” In time, this can […]
Which can show resonance?
Which can show resonance? Resonance is shown by toluene which contains alternate single and double bonds in a planar six-membered ring. Was this answer helpful? Why is ozone a resonance structure? Ozone, or O3 , has two major resonance structures that contribute equally to the overall hybrid structure of the molecule. Both structures account for […]
What is Gauss law for electric flux?
What is Gauss law for electric flux? Gauss’s law states that: The net outward normal electric flux through any closed surface is proportional to the total electric charge enclosed within that closed surface. How do you fix electric flux problems? Solution: To compute electric flux, we need the magnitude of the electric field, area of […]
