Why does helium make things float?
Why does helium make things float? Helium floats because it is buoyant; its molecules are lighter than the nitrogen and oxygen molecules of our atmosphere and so they rise above it. In the car, it’s the air molecules that are actually getting pulled and pushed around by gravity as the result of the accelerating frame. […]

Why water has high boiling point and freezing point?
Why water has high boiling point and freezing point? So despite its small molecular weight, water has an incredibly big boiling point. This is because water requires more energy to break its hydrogen bonds before it can then begin to boil. The same concept is applied to freezing point as well, as seen in the […]

How do you solve chain rule problems?
How do you solve chain rule problems? Solution: To use the chain rule for this problem, we need to use the fact that the derivative of ln(z) is 1/z. Then, by the chain rule, the derivative of g is g′(x)=ddxln(x2+1)=1×2+1(2x)=2xx2+1. Where do we apply chain rule? The chain rule can be applied to composites of […]
