Before we can understand why flasks are so fantastic, we need to understand a bit more about how heat travels.Heat is a kind of energy that moves around our world in three different ways called conduction, conv
the less force you need, but the greater the distance you have to use that force. The weight rises 1m, but now we have to pull the loose end of the rope twice as far (2m). How come?
How does heat enter the bloodstream? (a) Convection. (b) Conducti (a) Define blood flow. (b) Name two factors that influence blood flow. Why would prolonged elevations of blood aldosterone produce hypertension? Describe how oxygen and carbon dioxide are carried through the blood. If the ...
Equivalently, a number of corresponding dimensionless numbers, such as the Reynolds number Re( ¼ Lvj/n, the ratio of inertial forces to viscous force, where L is jet scale size and n is the kinematic viscosity), the Pe´clet number Pe( ¼ Lvj/k, the ratio of heat convection to...
(=Lvj/ν, the ratio of inertial forces to viscous force, whereLis jet scale size andνis the kinematic viscosity), the Péclet numberPe(=Lvj/κ, the ratio of heat convection to conduction, whereκis the thermal diffusivity), and the magnetic Reynolds numberRMe(=Lvj/Dm, the ratio of ...
Give an example to explain how it works. In biological systems, gases move by diffusion and convection. What are these, and when are they used? Explain briefly how an amoeba moves and describe its structure. Define or describe the following: Primary active transport process....
Hot oil is pumped from the top of the transformer through the heat exchanger (which cools it down) and back into the bottom, ready to repeat the cycle. Sometimes the oil moves around a cooling circuit by convection alone without the use of a separate pump. Some transformers have electric ...
Some vacuum cleaners do use filters like this to stop bigger particles of dust and dirt—but how do you catch smaller dirt particles as well? You could make a very fine filter or you could put several filters on top of one another, but in a vacuum cleaner they would clog up very ...
Explain how and why parts of the solar panel are designed to reduce heat transfer by convection, conduction, and radiation. Explain the formation of Fraunhofer lines using Kirchhoff's law. Explain how the bursting of cycle tubes is an adiabatic process. Is it an isoc...
Explain how energy moves through an ecosystem. Explain how heat is transferred by the following mechanisms: a. Conduction b. Convection c. Radiation Explain how squirrel tail flagging behavior and snake response to it benefits both squirrels and snakes. What is the relat...
