What is the process of liquefaction? In materials science, liquefaction is a process that generates a liquid from a solid or a gas or that generates a non-liquid phase which behaves in accordance with fluid dynamics. It occurs both naturally and artificially. What is liquefaction example? Liquefaction takes place when loosely packed, water-logged sediments at […]
What is law of conservation of momentum give an example?
What is law of conservation of momentum give an example? Conservation of Momentum Examples According to the conservation of momentum, the gun receives a backward momentum. The bullet of mass m is fired with forward velocity v. The gun of mass M acquires a backward velocity u. Before firing, the total momentum is zero so […]
How do we digest starch?
How do we digest starch? Starch breaks down to shorter glucose chains. This process starts in the mouth with salivary amylase. The process slows in the stomach and then goes into overdrive in the small intestines. The short glucose chains are broken down to maltose and then to glucose. Which organ is primarily responsible for […]
What are the significant figure rules?
What are the significant figure rules? To determine the number of significant figures in a number use the following 3 rules: Non-zero digits are always significant. Any zeros between two significant digits are significant. A final zero or trailing zeros in the decimal portion ONLY are significant. Which value from his calculation most strongly affects […]
What is the best pedaling technique?
What is the best pedaling technique? Here are their top tips to pedalling properly. Get your bike set up correctly. To see this content you need to update your cookie settings. Play with cadence. Aim for even power distribution – and try mountain biking. Practise single leg drills. Pull your pedals in semicircles. Work on […]
What is the freeze/thaw cycle?
What is the freeze/thaw cycle? What is a freeze-thaw cycle? A freeze-thaw cycle is when the temperature fluctuates from above freezing (32F), to below freezing, and then back to above freezing. This is considered one freeze-thaw cycle, and Minneapolis, Minnesota experiences several freeze-thaw cycles each year. What do freeze/thaw cycles result in? Freeze-thaw cycles can […]
What are the five assumptions of an ideal gas?
What are the five assumptions of an ideal gas? The ideal gas law assumes that gases behave ideally, meaning they adhere to the following characteristics: (1) the collisions occurring between molecules are elastic and their motion is frictionless, meaning that the molecules do not lose energy; (2) the total volume of the individual molecules is […]
What is the functionalist theory in sociology?
What is the functionalist theory in sociology? The functionalist perspective sees society as a complex system whose parts work together to promote solidarity and stability. This approach looks at society through a macro-level orientation and broadly focuses on the social structures that shape society as a whole. Why is functionalist perspective important? Functionalism emphasizes the […]
Why heating an air parcel causes it to rise?
Why heating an air parcel causes it to rise? Warm air rises primarily due its lower density as compared to cooler air. As the temperature increases, the density of the air decreases. As the denser air reaches the earth’s surface it spreads and undercuts the less dense air which, in turn, forces the less dense […]
What solutions are there to global warming?
What solutions are there to global warming? For example, improvements to energy efficiency and vehicle fuel economy, increases in wind and solar power, biofuels from organic waste, setting a price on carbon, and protecting forests are all potent ways to reduce the amount of carbon dioxide and other gases trapping heat on the planet. Are […]
