Is milk a Newtonian fluid? Newtonian fluids are those having a constant viscosity dependent on temperature but independent of the applied shear rate. Low-concentration liquids in general, such as whole milk and skim milk, may for practical purposes be characterized as Newtonian fluids. Is honey a non Newtonian? Honey is an example of a non-Newtonian […]

What does high or low specific heat capacity mean? A substance with a high specific heat capacity can absorb a large quantity of heat before it will raise in temperature (water has a high specific heat). A substance with a low specific heat requires relatively little heat to raise its temperature (copper has a low […]

How long does a nuclear fuel rod last? To make that nuclear reaction that makes that heat, those uranium pellets are the fuel. And just like any fuel, it gets used up eventually. Your 12-foot-long fuel rod full of those uranium pellet, lasts about six years in a reactor, until the fission process uses that […]

What are some safety measures during severe bad weather changes? Stay indoors and move to a shelter – either an internal, ground-floor room with no windows or an official shelter nearby. Board up windows if you know about severe weather far enough in advance. Avoid metal, electrical, and tall objects during a thunderstorm. Never drive […]

Which acid is present in our stomach? hydrochloric acid Does hydrochloric acid turns red litmus blue? In the given question, first the blue litmus paper was dipped in hydrochloric acid solution. Thus, the litmus would turn red. Further, when dipped in sodium hydroxide solution, it changes back to blue. Thus, the correct answer is B. […]

What products increase friction? There are two methods of increasing friction: one is by making the surfaces rough and the other by increasing the mass of the object that is moving. For example, the tyres of vehicles have treads (these are the ‘designs’ that you can see on the tyre surface), which increase the friction […]

What best compares radiation and conduction? The statements that best compares radiation and conduction are the following: both transfer thermal energy from warm objects to cooler objects and both can transfer energy through matter. The difference is that conduction is through direct heat transfer; whereas, radiation transfers heat through waves. What describes how radiation moves? […]

What is the quickest way to boil oil? When we add the letter B to the word OIL, we get the word Boil. So, it will be the easiest way to boil the oil. Why should you not add oil to pasta water? Do not put oil in the pot: As Lidia Bastianich has said, […]

Can you drive without airbags? It’s not illegal to drive without airbags, if your vehicle was manufactured before 1989. So the question then arises: What happens if you have no airbags and get into a crash? Airbags help slow down the change in momentum and help reduce the forces in a crash. How unsafe is […]

What is the most common ion of sodium? The most important and familiar sodium compound is sodium chloride, or common salt, NaCl. Most other sodium compounds are prepared either directly or indirectly from sodium chloride, which occurs in seawater, in natural brines, and as rock salt. What happens to a sodium atom when it becomes […]
