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 […]
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 […]
What is the difference between 1s and 2s orbital?
What is the difference between 1s and 2s orbital? 1s orbital is the closest orbital to the nucleus. 2s orbital is the second closest orbital to the nucleus. Energy of 1s orbital is lower than that of 2s orbital. 2s has comparatively higher energy. Does 3s have higher energy than 2s? In hydrogen the energy […]
What are the three regular views?
What are the three regular views? Typically, an orthographic projection drawing consists of three different views: a front view, a top view, and a side view. Occasionally, more views are used for clarity. The side view is usually the right side, but if the left side is used, it is noted in the drawing. Where […]
What is topic sentence in English?
What is topic sentence in English? In expository writing, a topic sentence is a sentence that summarizes the main idea of a paragraph. It is usually the first sentence in a paragraph. Also known as a focus sentence, it encapsulates or organizes an entire paragraph. What are the types of topic sentence? Type of Topic […]
What does the slope mean on an acceleration time graph?
What does the slope mean on an acceleration time graph? The slope of an acceleration graph represents a quantity called the jerk. The jerk is the rate of change of the acceleration. How do you represent parallel lines? To symbolize parallel lines in geometry, we use two vertical lines (or slightly slanted lines), like this: […]
How does flow rate affect heat transfer?
How does flow rate affect heat transfer? On the other hand, an increase in the heat transfer coefficient is observed if the area is maintained constant. Doubling the mass flow rate will result in a 92% increase in the heat transfer coefficient. However, there is a concomitant increase in the pressure drop, proportional to the […]
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 formula for lithium chloride?
What is the formula for lithium chloride? LiCl What does lithium chloride look like? Lithium chloride appears as colorless crystals or powder. Low toxicity. COLOURLESS-TO-WHITE HYGROSCOPIC AND DELIQUESCENT CRYSTALS OR POWDER. What does lithium chloride react with? Reactions with lithium chloride LiCl: LiCl (diluted) + 4 H2O = [Li(H2O)4]+ + Cl-. 2LiCl (solid) + H2SO4 […]
What is coefficient of rolling resistance?
What is coefficient of rolling resistance? The coefficient of rolling friction or resistance is the indication of how great the rolling resistance is for a given normal force between the wheel and the surface upon which it is rolling. Because of the various factors, the coefficient of rolling friction is usually determined experimentally. How do […]
