Why angular momentum of Earth is conserved? Earth moves under the influence of the gravitational forces of all bodies in the Solar System. The energy and angular momentum of Earth are conserved, because the gravitational force is both conservative and central. Is angular momentum is a scalar? Angular momentum is a vector quantity that represents […]
Why is some food heated unevenly?
Why is some food heated unevenly? Why Your Food Is Heating Up Unevenly Microwaves are sending radio waves toward your food, rather than heating it from underneath it like gas ovens. And people tend to pile leftovers with the densest part in the middle, which is why the outer edges will heat up, leaving the […]

Why is red the hottest color?
Why is red the hottest color? The hotter a material is, the more average energy there is in the light it emits. Room temperature objects emit light of relatively low energy in the infrared. This is invisible to your eye. Objects heated in a flame can become red hot, and this is probably where you […]
Does increasing volume increase rate of reaction?
Does increasing volume increase rate of reaction? A larger surface area per volume ratio increases the areas of contact between reactant particles. This increases the chances of successful collisions. Thus the rate of reaction is increased. Why does volume not affect rate of reaction? As the gas sample volume increases (e.g. as we add more […]
