Where is energy stored in a chemical reaction? Chemical energy is energy stored in the bonds of chemical compounds, like atoms and molecules. This energy is released when a chemical reaction takes place. Can you put too much insulation in an attic? But there may be a theoretical point of “too much.” If a home […]
Why don t all trees change color at the same time?
Why don t all trees change color at the same time? Trees are not so certain. Because the color change depends both on the weather in autumn and on the tree’s living conditions all year long. Trees’ fall color is a side effect of going dormant — the process of shutting down temporarily to conserve […]
What is the viscosity of liquids?
What is the viscosity of liquids? Viscosity, resistance of a fluid (liquid or gas) to a change in shape, or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow. Does fat affect viscosity? By my […]
What is the difference between resistors and capacitors?
What is the difference between resistors and capacitors? Resistors and capacitors come under the category of passive components, except resistors limit the flow of current in a circuit, whereas capacitors provide reactance to the flow of current and are used to store electrical charge. Can a capacitor replace a resistor? In AC applications, capacitors can […]

Does buoyancy depend on depth?
Does buoyancy depend on depth? Surprisingly the buoyant force doesn’t depend on the overall depth of the object submerged. In other words, as long as the can of beans is fully submerged, bringing it to a deeper and deeper depth will not change the buoyant force. It’s just that for sinking objects, their weight is […]
How is the sugar being dissolved in water?
How is the sugar being dissolved in water? Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules. The weak bonds that form between the solute and the solvent compensate for the energy needed to disrupt the structure of both the pure […]
Which country has no beach?
Which country has no beach? There are two such countries: Liechtenstein in Western Europe, surrounded by Austria and Switzerland. Uzbekistan in Central Asia, surrounded by Afghanistan, Kazakhstan, Kyrgyzstan, Tajikistan, and Turkmenistan. Which country has no sea? The maritime trading system has played a vital role in the economic development of the ESCAP region, but twelve […]
What is the oldest advertising medium?
What is the oldest advertising medium? Bronze plate for printing an advertisement for the Liu family needle shop at Jinan, Song dynasty China. It is considered the world’s earliest identified printed advertising medium. How old is advertising? The origins of advertising can be traced back to newspaper advertising in the 19th Century. In addition to […]
How do you know if a parametrization is smooth?
How do you know if a parametrization is smooth? A curve defined by x=f(t),y=g(t) is smooth if f′(x) and g′(x) are continuous and not simultaneously zero. Why do we have the second condition(simultaneously zero)? How do you smooth a dataset? Data smoothing can be defined as a statistical approach of eliminating outliers from datasets to […]
