State what happens to the linear dimensions of an object when it is heated. Explain why this is so. Why when steady state conditions apply, the rate of heat flow is the same? What is the second law of thermodynamics? What is the meaning of enlarging statistical concepts in the ex...
Spontaneous breakage of tempered glass is immediately noticeable because an initial crack exceeding a critical size (depending on its location within the thickness of the glass) causes complete fracture of the plate, typically into very small cube-shaped particles, also known as “dice”. Although t...
When most solids are heated, they melt into liquids. This behaviour makes sense in terms of entropy, or disorder: a liquid state is usually more disordered than a solid state, and higher temperatures mean that the particles within a material vibrate randomly with more energy. One exception, ho...
Answer to: When deoxyhemoglobin crystals are exposed to oxygen, they shatter. On the other hand, deoxymyoglobin crystals are unaffected by oxygen,...
How did we handle waste water in the 1900's? Early 1900s, 1 million people served by 60 sewage treatment plants for removal of settling and floating solids.Increased wastewater treatment meant increased residuals (sludge). Heated sludge digesters and use of gas. ...

In convection, energy is transferred through the movement of particles with different heat energies in a fluid or gas. Conduction works best in materials that are good conductors, such as metals. Convection does not occur in solids because the particles in a solid are closely packed and cannot ...
What happens when the thermal energy of a substance increases? What happens to thermal energy when the number of particles increases? What happens to the atoms and molecules in a substance as its temperature increases? What happens when an amorphous solid is heated? What happens when an ...
What happens to the particles of a solid when the solid changes into a liquid? A. They increase in size. B. They decrease in size. C. The attractive force between them increases. D. The attractive force between them decreases. When a closed tank of air is heated, ...
In paper tissue machines of the type described, the web passes over the dryer, such as a yankee drier, at a high speed of the order of 1200 ft. per min. As it leaves the dryer in passage to the creeping roll the formed paper sheets are dry and in a heated condition. This dry con...
