What are the limitations of Einstein theory of specific heat? The correct statement is that Einstein’s law fails to account for the low temperature behavior of specific heat of solids, even qualitatively, but at high temperature it goes to the Dulong and Petit law limit, which is an accurate description of the specific heat of […]
What is the other name for contour lines?
What is the other name for contour lines? A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. What are the features of contour lines? Characteristics of Contours Must close on […]
What is the relation between power and voltage?
What is the relation between power and voltage? Electrical Energy in Circuits In other words, Energy = power x time and Power = voltage x current. Therefore electrical power is related to energy and the unit given for electrical energy is the watt-seconds or joules. Electrical power can also be defined as the rate of […]
Do scientists speculate?
Do scientists speculate? Speculation is so easy and tempting in settings where it leads more to errors than to accurate information, that most often speculation in science is discouraged. But there is still a limited, useful, role for speculation in science. What does Aristotle say about science? The third and final division of science for […]
Is salt the solvent in a saltwater solution?
Is salt the solvent in a saltwater solution? In a saltwater solution, salt is the solute and water is the solvent. What is the solvent in a salt water solution? In a NaCl solution (salt-water), the solvent is water. A solute is the component in a solution in the lesser amount. In a NaCl solution, […]
What is significance of uncertainty principle in our daily life?
What is significance of uncertainty principle in our daily life? The Principle says that the position and the velocity of an object cannot both be measured exactly at the same time. At the size of objects seen in everyday life, such as a car, the Uncertainty Principle has no real application. We can accurately measure […]
What is wrong with carbon dating?
What is wrong with carbon dating? The group theorizes that large errors in carbon dating result from fluctuations in the amount of carbon 14 in the air. Carbon dating is unreliable for objects older than about 30,000 years, but uranium-thorium dating may be possible for objects up to half a million years old, Dr. Zindler […]
Why is Al3+ smaller than Na+?
Why is Al3+ smaller than Na+? Al3+ because they all have the same number of electrons, however Al3+ has the most protons and therefore greatest nuclear charge. In Al3+, the same number of electrons are being attracted by more protons in the nucleus, so the electrons are being pulled closer to the nucleus, reducing the […]
What is the order of structures that oxygen passes through?
What is the order of structures that oxygen passes through? Air then travels down the pharynx and larynx, through the trachea, and into the lungs. In the lungs, air passes through the branching bronchi, reaching the respiratory bronchioles. The respiratory bronchioles open up into the alveolar ducts, alveolar sacs, and alveoli. What is the pathway […]
