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 […]
Is 300 watts enough for a subwoofer?
Why does my heating work upstairs but not downstairs?
What is broaching in machining?
What is broaching in machining? Broaching is a machining process using a cutting tool with teeth that increase in size from front to back. In many cases, an entire surface (or multiple surfaces) can be finished in a single pass with broaching. The technique is most often applied to finish holes, splines and flat surfaces. […]
Is Bacteria living or nonliving?
Is Bacteria living or nonliving? Bacteria (singular: bacterium) are a major group of living organisms. Most are microscopic and unicellular, with a relatively simple cell structure lacking a cell nucleus, and organelles such as mitochondria and chloroplasts. Bacteria are the most abundant of all organisms. Do antibiotics weaken immune system? Will antibiotics weaken my immune […]

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 most common energy conversion?
What is the most common energy conversion? kinetic energy How does insulation stop unwanted energy transfers? Energy loss through walls can be reduced using cavity wall insulation. This involves blowing insulating material into the gap between the brick and the inside wall, which reduces the loss by air circulating inside the cavity, therefore reducing loss […]
Why is there no friction on ice?
Why is there no friction on ice? One of these theories is that friction causes the liquid layer of water to form on ice. Friction is the force that generates heat whenever two objects slide against each other. If you stand on ice without moving, no friction exists to generate heat, yet the ice is […]
What time of day is oxygen highest?
What time of day is oxygen highest? Even though there is an increase in carbon dioxide through the daytime on your block, oxygen is much more present at the beginning of the day. Is it normal for oxygen levels to fluctuate? It’s normal for oxygen saturation levels to fluctuate with activity. If your oxygen saturation […]
