Which of the following is an example of a chemical change? Ans: A chemical transition is the result of a chemical reaction, whereas a physical change is when the structure of matter changes, but not the chemical identity. Burning, cooking, rusting and rotting are examples of chemical changes. Is boiling water a chemical change quizlet? […]

What is numerical answer type question?
What is numerical answer type question? A ‘numerical’ question allows you to present a question that requires a specific numerical answer. This question type can allow a range of answers around the correct response, and can also deal with different units using a conversion multiplier. What is a numerical value? Noun. 1. numerical value – […]
Is there infinite water on Earth?
Is there infinite water on Earth? Water is a finite resource: there are some 1 400 million cubic kilometres on earth and circulating through the hydrological cycle. Only one-hundredth of 1 percent of the world’s water is readily available for human use. This would be enough to meet humanity’s needs – if it were evenly […]
What caused the widening of the war?
What caused the widening of the war? What caused the widening of the war? The war widened as the powers on each side tried to gain allies who might help them get the winning advantage. The stalemate on the Western front necessitated finding a different way to win the war. Why was the eastern front […]
How does speed affect wavelength?
How does speed affect wavelength? The speed of a wave is not affected by the wavelength of the wave. Wavelength and frequency are inversely proportional to each other. Does speed of light depend on frequency? The speed of light neither depends on the frequency or wavelength. The speed of light is also independent of the […]
Can a capacitor reach 100% charge?
Can a capacitor reach 100% charge? 4 Answers. As others have mentioned, for all intents and purposes, yes it reaches %99 charge after 5 tau. In the context of ideal circuit theory, it is true that the current through the capacitor asymptotically approaches zero and thus, the capacitor asymptotically approaches full charge. Will the charge […]

About 90% of the ozone in Earth’s atmosphere is contained in the stratosphere. How can […]
What is entropy and its properties?
What is entropy and its properties? Entropy, as we have defined it, has some dependence on the resolution to which the energy of macrostates is measured. Recall that is the number of accessible microstates with energy in the range to . Which is the correct formula of entropy? If the process is reversible, then the […]
