To detect potential energy sources within a well-known but complex system.
Fast moving reactant molecules or basically reactant molecules with a lot of kinetic energy.
Yes when something moves fatser than the speed of sound (or breaks the sound barrier) it makes a shock wave which unleashes an enormous amount of energy which comes in the form of a sonic boom. Hope this helps! :D
Reflection and absorption...most likely a combination of the two. In reflection the wave bounces back off the barrier and, depending on the incident wave and how it matches in phase with the reflected wave, the reflected wave could be enhanced through constructive interference with the incident wave or degraded through destructive interference. In absorption, the energy from the incident wave is taken into the barrier material. This typically causes the barrier to vibrate indicating the energy it absorbed. A barrier is more likely to absorb the energy when its natural frequency is some harmonic of the incident wave.
Radiant Barrier is essentially insulation that can be found anywhere where regular insulation is installed. Radiant barrier is foil and can often be seen covering duct work.
The question is this "what is an energy barrier?" My answer: First of all, activation energy is energy that is needed to start a reaction and barrier means to block so then energy barrier means to block energy.
needed energy
Energy is stored in the chemical bonds of organic molecules. The barrier of EA prevents these molecules from spontaneously breaking down and releasing that energy.
It is a barrier of energy that can be made from saiyan energy.
The Activation Energy.
Activation energy
Activated complex.
Aluminum foil can act as an energy barrier, but not a very good one. It is not very dense, therefore an electron (energy) can penetrate it. Because it is not very dense the molecules are not very close together it is not very good at passing energy along, which makes it a poor conductor, but it still can pass energy so it is not effective at preventing energy transfer.
it's not a type of energy but it's an energy barrier that prevents molecules from breaking down spontaneously
solar energy
This energy is called "energy of activation", it is used to overcame the energy barrier between reactants and products.
The activation energy is the amount of energy needed to start a reaction. If the reactants have less than that amount the reaction will not occur. In this way it acts as a barrier that prevents a reaction unless there is enough energy to break it.
